Ok well I installed an aftermarket head unit a few months ago in my 97 Ex. Well I didnt have the knowledge then about using a certain harness to keep OE radio and Keyless entry. Well when I bought the car used it did not come with remotes, but I figured as an EX it should. I have the lil button between the FM/AM and CD/Tape. Well im reading and I know what harness I need to plug in the old stereo, but what in the hell do I do about that green plug? I would think it has to be put into the old deck, but nothing I have read has confirmed it. I have seen that it is the plug that controlls the factory keyless entry, but nobody mentioned it when they posted in threads about hooking up a aftermarket stereo? I would again assume it just need to pulled back and installed into the radio like the adapter would. Now in the first link it shows a harness, but there are two seperate wires running off the part that plugs into the OEM radio anyone know? The second link the the one from Metra and its hard to see whats all included, but it doesnt appear to have the green plug. The third one is the Scocshe which shows the green plug, looks like an extension for far away relocates. So does anyone know for sure before I start ordering parts? Also my dome light will work after this correct, and how do I know if the car came equiped with an alarm or will it most likely just be the Keyless Entry? ANY help is welcomed, I really want this, but I want it done right the first time.
