Kenwood KDC-S3009, 1989 Jeep Wrangler

do it the old fashion way. use a dmm. it will tell you you constant, acc, ground, dimmer. a 9 volt battery will give you your speakers. the radio usually use yellow for battery, red for acc, orange for dimmer, i am sure you could figure the speakers outohio top first class installer

These are your vehicle wire colors:

Constant 12V+             Pink or Pink/White

Switch 12V+               Red or RED / WhiteGround                    Braided Cable or Vehicle Chassis                    FL+                       GreenFL-                       BROWN / RedRF+                       PurpleRF-                       Blue/Red LR+                       BROWN / BlueLR-                       BROWN / YellowRR+                       Blue/OrangeRR-                       Blue/White

Double check each lead in the vehicle with your meter before making any connections. If your vehicle wire colors are different, you can do as mecpinstaller suggested, measure for power first with your meter, then either use an analog meter or a small battery (9 volt or smaller works fine) to determine your speaker leads.

You can use the DMM but never assume that just because a wire is yellow it's a constant wire. If you did that in a Toyota then you would not get any power as this is the speaker wire. What you can do is buy yourself a wiring harness and this will simplify everything for you. They are only about 7 - 10 bucks and you can go here for the wiring diagram for your Jeep: http://www.bulldogsecurity.com/wires/wrangler87-90.htmJeff

well good point velocity motors, but alot of older vehicles actually get there factory harness cut into from hack jobs or backyard installers. a dmm will tell you everything you need to know. colors of wires mean nothing. it just the casing. if you touched a dmm to a speaker it wouldn't give you a reading.ohio top first class installer
