Had some questions as I'm getting ready to do the remote start install in my 97' 4runner. I'd like to get remote start as well as keyless entry. It does have power locks. I am installing a CM900S from Compustar.
Here's the wiring below with what I have and what I have questions on, please correct anything that you believe might be wrong. I've put in parenthesis the ones I'm unsure about.
12 V constant - White wire found in ignition
(12 V Light - Curious on if this wire is even needed? Or this just another accessory wire?)
12 V constant - White/Red wire found in ignition
12V accessory - Blue/Red wire found in ignition
(Selectable by Jumper Iginition - Black/Red wire found in ignition)
12 V Starter - Black wire found in ignition
12 V ignition (output/input) - Black/Yellow wire found in ignition
Ground - (Will tie into grounded nut)
Parking Light Output - Green wire found below fuse panel
Lock output - Red/White wire found left of fuse panel
Unlock output- Red/Yellow wire found in left of fuse panel
(Status output - Is this have to be used?)
(Rearm output - Not used?)
(Disarm output - Not used?)
Horn output - Green/Red wire in steering column
Foot Brake Input - Green/White wire in brake switch
(- Trigger Starter Input- Not used?)
(+ Trigger Starter Input- Not Used?)
Tach/ALT sensing input - Black wire in OBD2 plug

Some very minor updates. I used the (-) Parking Light wire instead of the (+) Parking Light wire you listed. It's possible the Tach can be found in the OBD2 plug, just test that Black wire to be sure. Check the jumper for IGN2 to ensure it's set for IGN.
