Not actually from the ECU, to the ECU.Well I'm trying to hook up my euro tail and have a few problems. I know there are several versions one with 2 and 3 sockets. Mine is the 2 socket version. Well here is the problem. I hooked it up the same way stock is everything functions fine just when the brakes are pressed the blinkers also come on and if the blinkers are used the brakes are blinking too. I know this happens because the way the wires are run from the brake ecu? I know I have to run 2 new wires from the brake ecu to the taillights to overcome this problem. Could someone post the location and the wiring diagram for the taillamps for a 164LS so I have something to go by?
You need to cut the turn signal wires from the lamps control unit. Light blue and Light blue-black. So these wires should not go into the unit anymore.
Then you run the wires all the way back to the lamps. So now it is directly from the Turn signal stalk through the cluster/relays and fuse box directly to the lamps (same as euro versions)
So now you need 2 per side resistors (20W 8Ω) to fool the ECU into thinking it has 2 bulbs back there still.
Use a common ground for both.
Then one goes to stop lamps (light blue-yellow/light blue -red) and one for parking lamps (yellow/black for left) (yellow for right).
So lets see if I can remember how it works:
-------turn signal lead(turn)----->resistor and to lamp harness--->ground
-------Light blue-yellow(stop)-------->resistor and to lamp harness--->ground
-------Yellow(parking)------->directly to harness
-------Black (ground)--------->directly to harness
On the two bulb harness you need a 7528 bulb( dual filament)
For turn a 7506 Bulb (single filament) Preferably ORANGE in color to be correct.
Top of harness:
- pin 1: grnd
- pin 2: stop (make sure first it could be parking)
- pin 3 turn
- pin 4 parking
Hope that helps, call if you need help.
- Pin 4: turn signal
