ABS Transplant
 

I was hoping someone may be able to help out.

The sierra is a 3 door 909 shell with a 84 4i loom.

Bought a complete ABS system [told] from a 2wd saph cos, 2 relay type.

Attachment 136637

Attachment 136638

The pump and valve block and all bay wiring and wheel sensors was all straightforward, I read on here you need the orange relay. So got one and a fuse box which I needed anyway from a saph.

This only has 3 conectors left,

1 A 2 pin plug wires are brown/red and black/grey.

Attachment 136639

Dash warning two orange leds, and are connected now.

2 A 5 pin with three used red and a brown/black and a yellow.

Attachment 136640

Diagnostic connector and not used ?

3 A 8 pin plug with 6 used.

Attachment 136641

1 Yellow
2 Yellow/White
3 Brown/Yellow to fuse 22 powering dash warning lamps
4 Black
5 Black/Green
6 Black/Grey linked to red dash warning lamp

The orange relay. Removes + while cranking pos 3,is this needed with this ecu?

Attachment 136644


pin 30 had a black wire joining multiple black / yellow
pin 87a had a red wire
pin 86 had a black / green
pin 85 had a brown gnd

I have a few wiring diagrams and the colours don't match up and only five wires on conector 3 the only one with the right number of wires is such poor quality it's no help.

The system has been running (temp ignition feed to yellow on plug 3) and the brakes are bled.

So feel free to point me to a diagram relating to this ecu or help me work through it one at a time.

Cheers Ade
