Hi, I just Installed a ProStart remote starter from Can.Tire, on a 2000 Pontiac Sunfire Std.now I need to Install the Patsk - 300 GM Passlock 1 & 2 Bypass Module and don't understand the small amout of information diagram. The first double pin connector, Red 12 volt fused....done
Don't undrstand the Ignition out, Yellow ? Also the second small 7 pin connector:
Green - Ignition.....which one?
Brown - Starter Input (n/a) for passlock 11)....?
Grey - (-) out when running....?
Yellow - Cranklow (n/a for passlock11)
Red - Data wire (car side) Installed
Blue - Data wire (Key side) Installed
Black - IPC Ground...assume it's just a ground. It seems to me that this unit should be installed in series with the remote start
I've never Installed one before and would appreciate any information.
The actual diagram can be found at.....https://www.infinite-motorsports.com/AutoStart/pdf/inst_patsk.pdf Thanks Ron.

Don't undrstand the Ignition out, Yellow ? Goes to your PINK wire in your ignition harness Green - Ignition.....which one? PINK wire in ignition harness
Grey - (-) out when running....? Look for a wire in the wiring diagram that describes a wire that sends a negative signal ( GROUND OUT WHEN RUNNING ) only when remote started and hook this wire up to the GREY wire of the module
Black - IPC Ground...assume it's just a ground. This is a ground wire that you attach to the same ground as the remote starter
WOW !! That is one confusing module to have to get your resistance correct  Good luck and if you need more help.... just post it here. ------------- Jeff

Thanks Jeff,
But I still don't know where the Brown Start Input goes....
and the Yellow - Cranklow should go.?
From what I'm reading, it say's Brown - Start Input (n/a) for pass lock 11
and the same for the Yellow - Cranklow (n/a) for passlock 11
So I am assuming I have a passlock (1) and these wires should be hooked up.
That's something else, how are you suppose to know if it's a pass one or two?
it looks like a pass 1.....because the resistance didn't change while the car was running.
Thank for your help. Ron

Hey Ron, you actually have a Passlock II system in the 2000 Sunfire so you don't need to hook up those wire according to the wiring schematics that you gave. Good luck and post if you need help. ------------- Jeff

If you don't have a second ignition, which a 2000 Sunfire doesn't, you shouldn't use the main two wire harness, just the seven pin one, if you use the two pin harness with the ignition out wire and 12 volt hooked up, you can run into trouble with the autostart not shutting down after the ignition is turned on with the key, if the vehicle has a second ignition, ie. 1999 sunfire use the two pin but put the yellow ignition out to the second ignition....I've learned from experience....hope this helps, tech_advice aka KaptKanada...

if you want a passlock bypass module that you don't have to worry about the resistance( it knows the resistance automaticly) and is very easy to understand and install get a DEI 555L from any DEI dealer, very easy instructions for both the passlock I and the paslock II systems.

Hey, thanks for all your help, now that I've got the Passlock installed my problem is
the pro start remote, if I use the same (-) out from the car remote for the relay I used to by pass
the clutch the car will not start just wind over, if I just use this neg. out ground for the bypass clutch
the car will start by remote. But then it will also start without pushing the clutch in when not using the remote
and that's not good, also the parking lights flash, we tried using a diode so the power wouldn't back track and
still won't work.
The relay for the clutch is just a std. type 30 amp. powered the #30 with the yellow Ign. # 85 Ground and then
just used pin # 86 and # 87 as a switch for the clutch.
Any help ?......I'm loosing my sole over this one.

Hi Ron, if your relay connections are as you described, the lead you cut to attach to these two terminals on the relay will never have contact with each other (causing the car to start without pushing in the clutch) and the coil of the relay will never be energized as you described. You need to connect a (-) pulsed output from your alarm or keyless entry to trigger the remote start and connect the (-) sensor bypass output of the remote start to terminal #85, connect terminal #86 to 12V+, connect terminal #30 to one side of the clutch switch and terminal #87a to the other side of the clutch switch. If your remote start unit does not have a (-) sensor bypass output, connect the ignition output of the remote start to terminal #85 of the relay for the clutch bypass and connect #86 to ground, and connect #30 and 87a as above. With the same remote start ignition output that you connected to the clutch relay, connect it to a #85 of a second relay, connect #86 to ground, connect #30 to the vehicle's ignition lead, and connect #87 to 12V+ . Do not connect the ignition output directly to the vehicle's ignition lead as this will activate the clutch bypass whenever you use the key to start it. If you need a diagram, let me know. the12volt

Hi Ron, one more thing, are the two leads at the clutch switch normally closed or normally open? If they are normally closed, wire it as I described above. If they are normally open (most are), connect one lead from the clutch switch to terminal #30 and connect the other lead of the clutch switch to terminal #87. the12volt

You don't need a relay to bypass this car, it has a type1 clutch switch, just hook the starter output from the remote start to the purple wire at the clutch switch and your problem should be solved....Chris

Thanks tech_advice, so now If you (Ron) connect the starter output to the vehicle's starter wire and the clutch switch, the vehicle will still start with the key without pushing in the clutch so you'll still need to isolate the clutch switch from the vehicle starter wire with two relays if you do not have a shock sensor bypass output. On the first relay connect #30 to the purple wire of the clutch switch. On the second relay connect #30 to the vehicle's starter lead. On both relays, connect #85 to the starter output of the remote start, connect #87 to 12V+, and connect #86 to ground. the12volt

BTW, if you do have a shock sensor bypass output, you'll only need one relay as this output is usually a (-)200mA output. Connect the shock sensor bypass output to terminal #85, connect #86 and #87 to 12V+, and connect #30 to the purple lead of the clutch switch.

Errrr.... one more thought, if you do not have a shock sensor bypass, you can just use one relay instead of using two as I described above. You can connect the output of the remote start directly to the purple wire of the clutch switch (as tech_advice said) and to terminal #85 of an SPDT relay, connect #86 to ground, connect #87 to 12V+, and connect #30 to the vehicle's starter lead. Using this relay will isolate the clutch switch from the vehicle's starter lead and prevent the vehicle from starting with the key when the clucth is not pushed in.

Bah @ 2 hours of sleep...final thought...just thinking about what tech_advice stated...TYPE 1 Switch. No relays are needed to isolate the clutch switch from the vehicle starter lead...they are one in the same at the switch. oO(..DOH!...my bad, sorry for any confusion)

Hello, Re: my post dated April 3/02 5:52 pm....The way I explained how I had the relay hooked up was wrong in that post
This is how I have it installed now, the remote starter works fine but the car will now start with just the key and without the clutch.
# 30 and #87 are connected to the clutch switch wires, # 85 car ground and # 86 12 volts from the yellow Ignition wire.
Which of your reply's would work best.
I can't seem to get a good pulsed ground to the relay, the ground out is working the passlock module and won't work on both the
car just cranks then stops.
Thanks again
Ron

Take the relay your using on your clutch out all together, run the starter wire from your remote to the purple wire on the clutch switch, this will give you a direct line to the starter, without compromising the clutch switch and will free up the neg out when running lead for your passlock....This will also cure your problem with the car starting with the key and no clutch, because when your grounding that relay it gives the clutch a constant bypass when the ignition wire is charged, to the car it looks like the clutch is pushed in and making contact.....hope this helps, Chris...
