Topic: remote start on 78 nova

Subject: remote start on 78 nova
Date Posted: February 26, 2014 at 10:39 AM

Ok I gave a 78 nova original engine 6 cylinder 250 and I want to put remote remote start on it. This install is basic but driving me up the wall. So Im basically don't want to use the power locks or any functionality of the alarm. Just the triggers for the doors hood and trunk. I don't need help with those because they don't exist so I will have to add them into the car. What I need help with is the ignition part. I watched a few videos online and they said I need a accessory, ignition, constant, starter wire brake wire and tach. The engine is of course not fuel injected so I put a solenoid on the throttle cable to push for gas and I'm going to use the trunk feature on the alarm to trigger the solenoid. The alarm I'm using is a viper 5X04

Carbrueted engines require interaction by the driver to get them started. Ie, the driver operates the throttle as required to get the engine started. Unless the carb is perfect, and will always start with the same travel of your solenoid, in any weather, regardless of engine temperature, you're going to be frustrated with time-outs and no-starts.

There's a reason instructions and recommendations for Remote Starts always include "for installation on fuel injected engines only". Because EFI engines start reliably under a wide spectrum of conditions.

I understand that I got the carb rebuilt and I'm keeping the factory key option I just wanted to know what wires I actually needed

I'm doing this from memory. I don't think the colors have changed over the years.

On the Nova Ignition Switch:

Pink = Ignition
Purple = Start
Brown = Accy
Red = (B+)
There may be a dk grn = "bulb test" do not connect anything to this.

Thanks so i don't need the brake wire and tach to use the remote start also for the starter I dont need to connect a wire to that. as for the colors you saI'd its correct I see them going to a hsrness on the steering column but I have another another two purple and purple white going to a harness COnnector on the lower end of the steering colum

Most RS DO need a brake switch. And a tach wire may help you with more reliable starts with a carb'd engine. And if you don't connect to the starter circuit, how is the RS supposed to function?

Again from memory:

Brake = white wire at brake switch or turn signal switch connector.
Tach = A 1978 should be the GM HEI distributor. A big-azz thing. On the 'leg' that sticks out, there's a pink wire marked "IGN" and next to it (looking up) a terminal marked "TACH". Use this terminal for tach.

The pur and pur/wht wires "lower on the steering column" are the neutral safety switch. Use the purple wire at the ignition switch for starter.

You also need the hood pin as a safety input. Put one in.

Thanks for the info after you wrote the colors and told me to test them I went and looked at my two service manuals (organized wierd) and both books comfirm your right. This is my first alarm install but I have experience doing other things.I'm go look at the distributor cable . As ffor a hood pin I'm going to do one as well trunk and doors. The door harness I found. the hood and trunk I'm create the harness for them

I checked the wiring cods for the tach and its Brown. Under the dash there is a brown and a brown and white wire .does that tach wire goto the steering colum. Sorry for all the questions I just want to do this right the first time

No, the tach wire shouldn't be at the steering column. If your vehicle has a tachometer then you would be able to use the signal wire for it. If it doesn't, then it will be at the distributor cap... as Davep stated. The BROWN / white I believe is a resistance wire for the alternator. Brown is used for parking/tail light circuits, accessory circuits, heater circuits.

Ok I found the tach at the cap that's a no brainer. The thing is I'm looking a wire shematic online and it gives color codes and the book doesn't show the steering column wiring only shows the starter

so you need the wiring for the turn signal/hazard switch on the column?




Posted By: still_walkin
Date Posted: February 28, 2014 at 8:39 PM
The book has that .I don't plan on using those all. The car is all manual so I'm use just the remote start and the trunk release I'm use to trigger my solenoid I wired to my carb for the remote start. This install is gonna be basic I just dont want to mess with the old wiring too much. As for door triggers I'm tap into those tho

Ok I'm on the trunk release and the wiring legend says neg but on most trunk release its positive .also on the tach the wiring diagram link about it says its brown am I correct

You'll need a relay to convert the negative low current output to a positive high current one. Is the coil integral to the distributor cap or external? If internal, the cap may be label with TACH. There would be a male terminal on the cap. If external coil, use the (-) terminal.

Its labeled tach but no wire coming out on that end. Also the siren the wiring legend has a neg but the siren itself has a postive and neg the neg wire looks like it supposed to be grounded it has a o ring connector

Use a mirror or feel if there is a terminal on the cap. On the siren, I thought DEI used positive siren outputs.   Connect brown to red, ground the black, see if siren sounds.

Ok I'm try the siren and see what happens I grounded the siren and hit to the pos lead and it worked so on the alarm what do I connect the pos wire to on the alarm

On the wiring diagram the trunk release is neg but I thought it was grounded thru the car and had a positive lead coming out of it

DEI siren output is brown connect to red on siren, ground RED / black on siren.

I got that I'm talking about wiring straight to power ground .in the post above it states connect the sirens positive to the Brown wire on tbe distributor. I got it all wired up and I used the cars factory radio harness for the relay for the pop trunk function and it kept blowing the cars light cluster fuse. So I'm thinking tapping in the main ignition accessory wire for the relay

I'm usually not one to chastise or critic another. I never stated to connect the sirens positive wire to the brown on the distributor. The brown on the alarm module connects to the positive wire (red) on the siren. You asked about wiring the trunk release, then added a question about the tach connection. As for the fuse blowing, which fuse is blowing? Your solenoid used is what type? Does it have any specifications/ratings? Using common sense as someone with 12volt background I would hope has, the two are entirely unrelated. If I were you, I'd do some research on installing an alarm/remote start system. I believe that may assist you more as I can't see exactly what you are doing.

As in the solenoid I had it laying around so I believe its a 30 lb. You told me to wire the solenoid to a relay .the relay needs a acc wire so I used the factory radio harness and it worked for a lil after mesing with the pop trunk feature the dash display fuse blew so I disconnected it and figure I use the main acc on the column. As for doing more research on RS I agree I pulled the alarm and I'm start from scratch.

Not knowing exactly which solenoid you have, I'm guessing you overloaded the circuit. It would be best for the solenoid circuit to have its own independent fuse with wiring appropriately sized. A battery (full time) circuit as compared to an accessory (switched) circuit may work better. It would allow operation of the solenoid at any time. And of course now rereading, your tach query also had siren questions added to it.

Pretty much the deal with this car is everything is manual so if I add something I have to run straight from the battery. the only acc is the radio or the main from the steering column . I could tap into the fuse box but I've been avoiding the cars electrical system due to age and lower amperage requirements. I was thinking run a 8 guage from the battery and feeding the alarm off that as for a acc I haven't figured tht out how I'm do that.
