Trying to hook up last few wires and not sure what they are

Hey I'm not an expert at remote starts I've only hooked up one in my life I have two of them one in my Durango & one in my Dakota Dakota was installed by best buy & Durango was installed by pc richards I'm not positive but I think tach wires are the same color on all remote starts and mine are purple the tach wire on the Durango is hooked to the #3 fuel injector wires & the Dakota wire is hooked to the coil but the tach wire is purple look back at installation directions you might have a defective remote start unit remember I said I'm not an expert I'm just going. By what I have I really hope this helped you oh by the way the van has an automatic tranny right? Good luck

something not hooked up look around make sure everything is hooked up a little 420 dude

the pink wire is the parking brake wire... so should be hooked up to the paqrking brake...
OR , you can put a switch on it to bypass the safty feature.

you need to hook up to a scan tool to reset it completly

well if it is cranking its not starter or battery . maybe check to see if fuel pump is working .check fuses. you should be able to hear pump run for a few second . if pump working maybe fuel filter or sensor like throttle position ,air idle sensor. make sure all wires are hooked up on alternator & starter . no vacuum hoses off any where . is check engine light on ?

Are you installing a flat 4, or other connector? Before we go too much further, I can tell you how to splice wires to what etc, but are you aware that they sell an adapter plug, that you just plug in to your current wiring harness, like a "T" shape, and simply plug your trailer into it? Sure makes it easy, as well as removable if you want to remove it after.

I installed an aftermarket trailer wire harness and hooked it up to a boat that was not grounded or made a bad circuit. This resulted in a very strange electrical failure to the point the vehicle shut down and I had to disconnect the trailer harness and restart. I also washed my engine once and somehow spayed water through the firewall into the ecm on the drivers side kick panel... Again strange electrical problems occurred, this could be identified by the loss of the keyless entry

Pull the sensor see if oil pours out if not then buy a tube of blue lock tite from a auto parts store and add a few drops to the sensor screw in and let it set up then hook up it should then not leak anymore.

Try hooking up a mechanical gauge to make sure you have a problem.
