just after the wiring for the pins on the back of the fairmont clock? any help! please

AcidBurns

These are the instructions I used, from a thread 5 pages back...


Well I thought I lost the wiring diagrams for my trip computer install but guess what I found??This is for Early and Late production for Ghia and Fairlane.
Looking at the front of the connector to the trip computer with latch up top from left to right.
..Pin 1 BLACK to ground,ground located in clock connector which is clipped into the trip-computer blank. Has 4 wires going to it.
..Pin 2 GREEN with VIOLET fuel injection feed,located at ECU (green/yellow i think) .Second pin up is black (ground)
...Pin 3 BLACK with WHITE wire to LCD dimmer doesn't work anyway don't connect it. (only for fairmont)
..Pin 4 YELLOW with BLACK goes to battery power,yellow wire at boot release. (theres a wire behind the clock for this).
..Pin 5 YELLOW with GREEN wire fuel gauge signal.Big yellow connector behind instrument cluster goes to yellow and green wire.
..Pin 6 BLACK ground vehicle earth,other balck wire at connector behind trip computer blank.
..Pin 7(under pin 1) RED OR WHITE to white behind cluster not red as this is the return wire.
..Pin 8 RED with GREEN ignition power 15 amp fused,same small black connector with 4 wires behind trip computer blank.
..Pin 9 Spare.
..Pin 10 BROWN wire park lamps goes to demister switch 12v supply when lights on. (i thought there was one at the clock, there wasnt. use the one from the wagon's wiper switch, which is unused in the EA, and is a whiteish bigger connector).
..Pin 11 WHITE and BLACK buzzer.Only cars that have this is Fairlane and Ghias, they hook to the dash. it should go off when the lights are left on ignition off and when fuel is low it will beep at 80km to empty 60 to empty,40km to empty and 20km.The trip computer has its own internal buzzer and uses B+ and signals from the speedo and ignition to calculate the buzz.A real bonus when it was not meant to work.
..Pin 12 Spare.



---and this---


2 Black wires (one of yours has brown spots) - Ground
Red wire - To speed sensor (can be found behind dash) - leave disconnected if unsure
Yellow/green - Fuel sender wire
Red/Green - To ignition power
Yellow/Black - To batt power
Brown - To the park light circuit (for warning beep)
Black/white - To dimmer (I ignored this wire - only for use in Fairmont)
White/black - To dash warning system (I ignored this wire - For Fairmont again)
Green/violet - To Pin34 on ECU (this wire was actually green/yellow on my loom

When connected up properly, you should get your
INST L/100KMS at 99.9 with ign on and car not moving.

thanks for your help buddy, ive got it going but when i start the car the light turns on and then when i turn my headlights on, the light in the clock turns off. can anyone explain what to do?

Acid, I have no idea what could be going wrong, but i think he has the clock thing. Not the t/c.

What DO you have 'first car'?

Sunny, by it being a 'fairmont' clock, I am quite safely assuming the trip computer... As to why it's not working right, I wouldnt have a clue... I barely got mine working, then with the info above, I managed to finish it off... maybe you have crossed the lights/dimmer wires or something?

sorry for the confusion guys, it is a ea fairmont clock, not trip computer. i know its straight forward to install, and i have just pluged it in, although when the ignition is turned 'on' the light on the clock comes on which is fine. but when i turn the headlights 'on' the light (illumination) turns off. im not sure if this is a factory aspect, but i waas hoping i could wire it as you guys have with the station wagon wiper buttons - brown wire, thanx
