1986. 4+3. has after market keyless entry installed. Has both of the door ajar pressure switches removed. I plan on replacing them. Though I have to say I am a little concerned why both of them have been removed, it seems a bit questionable. Perhaps he had issues with the keyless entry

goal is to replace the walmart brand head unit that the previos owner installed. speakers have all been replaced.


given the above, i have two weird things i found that previous owner had bubba'd and id like to un-bubba:


1. yellow wire that feeds constant 12v for memory to head unit was merged into the red keyed 12v power supply. That would imply that the stereo would never have kept radio presets or clock. i dont know as i never checked before i tore the interior down for refurb. the only yellow wire i can see that looks like it was cut is shown in this picture. there a few unused plugs sitting nearby. i suppose a great test for constant 12v would be to put the boltmeter on that wire and see if it is hot? you can see the second picture shows how the yellow was merged into the red (using a white wire to get there). the previous owner also had one of these feedback loop thingys and i have elected to use it again.

this is the only yellow wire that looks like it was cutoff. i will check if it is hot
the yellow was spliced into the red like so.



and 2. orange wire that controls dimmer for head unit.

it was severed at the back of the harness adapter. the only orange wire i can find is in this photograph.

it comes out this white plug and has been turned around and been crimped into a white wire.

note that the severed yellow cable and the orange wire come out of the same plug.





im totally inexperienced at electrical. ill figure it out but thought id post this to bounce off you guys if any guidance and thoughts come to mind. cheers.

 

bit more info.

the orange and yellow do infact come from the same white plug.

the yellow comes from the pink/white wire.

it iis hot 12v all the time. so i found where my yellow wire was supposed to be attached. not crimped into the red keyed 12v power. so i will make that connection.

the orange is as i feared, related somehow to the keyless entry. it is fed by a brown wire.

the orange wire looks to have been intended for the dimmer switch control on the factory stereo. but it was snipped and sent over to a black box that i assume is related to the keyless entry. why would keyless entry need a dimmer line? maybe i am wrong about orange being dimmer line.

that orange i think took the dimmer signal to the head unit. it was clipped and re routed to come into the black module which i suspect has to do with the keyless entry system.
here is a pic of the orange wire, which was changed to white in the process to make leap, as it lands over at the suspected keyless entry module??

 

Good luck!

 

Does your keyless entry only do the doors or the hatch too? When I purchased my '92 it only opened the doors, but there was a button on the remote for a trunk/hatch. I already had things apart for a stereo install and so found the manual for the keyless entry and was able to hook the grey wire out of the controller to the hatch release switch. That unit looks similar to mine. They really don't put any identifying information on the system to aid in figuring out what it is.

 

Your car looks like it was a factory non-Bose car which should make things easier. Is there another unused plug with black, red, and grey wires in it ? Did the PO install new speakers and wiring for them ? If all the stock wiring is good up to the plugs you can use an adapter (Metra PN 70-1677) to make your life much easier. I would scrap the entire aftermarket keyless system entirely, it will probably cause more problems than it is worth.

 

there was a number on the back of the keychain that I called. It turned out that it is in Audiovox unit. At least that's why answered the phone and gave me a very very good technical support.

he walked me through some diagnostics and I hate barking dogs is bang on

The power keyless entry in the car is an awesome feature that I really enjoy. I'm just going to hook up the wires correctly, the only two that work incorrectly installed by the always on direct 12 V battery memory wire, which is that pink and white striped one that goes to the yellow one on the aftermarket harness. And the second one was the dimmer switch which is commonly left uninstalled on aftermarket situations.
