Message Have you checked by the ECU, under the dash, behind the glovebox, or behind the radio for the aftermarket alarm computer? If it's still installed and not a POS, you could just order a new set of transmitters and use it.

If you're going to remove it, how well can you follow wiring diagrams? It will be helpful to have the right year FSM to identify wires by color and harness location (this page has most years). After disconnecting the battery, I would peel back any electrical tape and start tracing the aftermarket wiring back to where it taps into the OEM harness. Depending on how they installed it and what features they used, you will need to cut off the aftermarket wiring, possibly reconnect the original wires, and solder and heatshrink it all back together. In the area pictured they probably tapped into the parking light circuit, and with that relay, maybe a starter or fuel pump kill, or door locks.

If you are handy with a multimeter and can read the wiring diagrams and have the time to carefully undo the install, it shouldn't be too bad. Make sure to take pictures along the way in case you can't start the car afterwards, so you can backtrack and find the problem much easier.


RTFSM - Read the Factory Service Manual

Purpose of site is to archive Z information. It is found by using search. Same reason you go to a library to read books to research a topic instead of standing in the library lobby shouting your question hoping someone has read the books your answer is in. - LordZ
