What parts are needed for 97+ front end update???


Recommended Posts

I just finished this on my 88 MJ, I can give you a wiring "diagram" to save you the hassle I had of trying to sort out all of those wires. There's 10 wires on the new harness, and like 6 or 7 on the old one. So far, everything seems to work.....

Which wiring diagram? I have an 89 and 99 FSM and here are the headlight harness colors:

1999

Connector C106 driver's side main harness to headlight harness looking at the back of the headlight side connector with the tab on top Pin 1 is on the right top pin 8 is on the right bottom:

 

1 empty

2 red - Left headlight low beam power

3 light green - Left turn signal power

4 black - Right headlight park/turn light ground

5 empty

6 red/orange - Right headlight low beam power

7 brown - Left parking light power

8 light blue (w/ fog lights only) - Fog light power (to bulb)

9 violet - Left headlight high beam power

10 tan - Right parking light power

11 black - Left headlight park/turn light ground

12 red (w/ fog lights only) - Fog light power out (to relay)

13 violet/red - Right headlight high beam power

14 dark green/yellow - Right turn signal power

 

1989 headlight wiring. Main harness to headlight harness connector on driver's side. Looking at the back of the connector on the headlight harness side with the 'ears' on the bottom, Pin 1 is left top and pin 6 is right top.

 

1 empty

2 white - headlight high beam power

3 grey - left turn signal power

4 dark blue - parking light power

5 black - ground

6 red (w/ fog lights only) - fog lamp relay power in

7 light green - headlight low beam power

8 brown - right turn signal power

9 empty

10 light green - (w/ fog lights only) to fog light relay signal power

 

Hope this helps.

Joe
