H-E-L-P-!

I'm @ my wits end trying to get the RS to work in the vehicle. Below is how I currently have the vehicle/bypass/& alarm system wired. All the alarm functions work, doors lock/unlock, interior/exterior lights do their things. However when remote starting the accessory energizes, but I don't get any dash lights and truck never cranks. If I unplug the ignition plug, then I have dash board lights like a keyed start, but starter never engages, even with the transponder key in the ignition (plugged & unplugged.) I have verified that the XK532 is programmed, because I can remove my transponder from the key and hold up the XK532 to the ignition and the vehicle will start & run. I never see 12 VDC+ @ the starter wire while trying to RS, where is it supposed to come from, my only thoughts are the RED / Black (H3/9) which is not hooked up???

I did read somewhere that the XK532 needs a 1Kohm resistor, but where, and why?

Any input and assistance is greatly appreciated.

Checked MUX resistance and during RS no different resistance were sent by the XK532. Key start had resistances @ start & run.

A couple of things.

Is the XK532 flashed withCHDL7 v3.00 firmware?

The XK532 Pink Starter wire should go to the Viper H3/4 Violet wire.

H3/2 should go to +12v constant.

H3/1 should go to the Pink/White Ignition wire at the trucks ingition harness.

Kreg357 -

1) Yes, the XK532 is CHDL7 Firmware, not sure what version though.

2) I did wonder about that connection and did rewire that way but truck didn't start so I returned wiring back. This was before finding the wrong pin connection mentioned below. Could this be causing the ACC issue?

3) Any reason why? Nothing is connected to that relay that I did.

4) This was connected correctly.

Thanks for the response.

I have figured out that the pin out was incorrect for H2/10.......in removing extra wires in the connectors I had removed the H2/10 and re-installed it in the wrong position. posted_image This was preventing the Status Output signal from the 5901 to the XK532 for the start process.

RS is working now!!!!! posted_image Truck starts, runs, all safety circuits shutdown the vehicle correctly. The only thing is that the Air Bag light stays illuminated while running in RS, once I take over w/key it turns off. Also, now the accessories are not powered during RS. Any ideas? H3/2??? Or does H3/3 need to be connected to the vehicle somewhere? My diagram for the truck says that the ACC is the same as MUX wire, so the XK532 should be sending the correct resistance for ACC to run correct?

Only changes in above wiring is H3/9 is connected to +12VDC now.

Yes, my typo/error on H3/2. Meant H3/9. H3/2 is not necessary if you're not using the Flex Relay.

Yes again, the XK532 should supply the correct resistance to turn on ACC at the correct time. You could see if that is the problem by connecting one side of a 610 ohm resistor to chassis ground and the other side to the trucks mux wire after it's remote started and running.
