ECU Loom

Can anyone identify these ABY motronic connectors which attach to the main fuse board?







Cheers Jon.

Yep... That 6-pin connector looks like T6r on the schematic.

Blue/Yellow wires from F66 & F76 into Autocheck via T10/4. Track 86 on ABY circuit.

Red/Brown wire connects radiator relay pin 4 to afterrun controller pin 5. Track 107.

thanks paul, saves me trauling through schematics for hours on end

I can't find the green one yet in T6r...

The other single spades are more tricky... Could be that the two red/black wires connect to the fused side of S21 in the main fusebox for the afterrun pump and power to the black OBD plug. Thats track 110. You need to buzz that one out - if it connects to pin 1 on one of the 8-pin circular connectors then its the afterrun pump supply.

And the single red spade could be fused side of S27 in the main box... If it is, then it should connect to pin 18 on the ECU. Look for track 73 in the schematics for that one.

Still stumped by the green wires for now

I have a spare ABY loom in the garage---- might have to investigate later this week!

[Jon441cc]

The green wires have black stripes, you cant see them in the pic

[Jon441cc]

The green wire in the 6 pin connector has a Red stripe.

Ohhhhhhhh now you tell me...

Only thing of interest that is red/green is IMMO related... Gimme more time on that one.

As for green/black spade I suspect its also IMMO related and/or could be OBD pins from IMMO and ECU.

[Jon441cc]

ive located fused S27 and yes single red spade is connected, pin 18/permanant 12v.


Both green and black wires go to S24 and S28.

[S2central.net]

D'oh yes of course on green/black - from the fuel pump relay (J17) on tracks 8 & 9. I can see it now in the daylight

Im sorted now paul

Green / black goes to terminal 87a on the fuse board.

Is Fuse board pin H87f = 12v fuel pump supply.

Connector T1f ?

[S2central.net]

T1f connect reverse lights to the reverse light switch in the gearbox !

Fuel pump relay is J17 at position 10 (ten) on main fusebox... 12V supply to that is pin 48/30 on the fuel pump relay. This is an always-on unfused connection.

H87f on the fuseboard is the fused side of S13 (thirteen) which is activated when the fuel pump relay is ON. This is track 20 on my schematics and it links to track 42 with a green/yellow wire to G6 (aka the fuel pump) ! Tada

H87f is double teamed with B87f on the fusebox by the way - could be useful for something I guess...
