I used female Molex sockets with a couple of inches of wire connected to each - got them from old PC power supply connectors actually - but I did it the hard way - ie. all sorts of trouble getting the little buggers to fit into the back of the ECU connector - then after I'd done it all I discovered that the red part on the back of the ECU connector apparently comes off somehow and this makes fitting the Molex sockets much easier I believe.


Ahh cool, bascially same thing I did.

f**k if I know why it aint working yet lol...

No, not really I've done them and the voltages are right.

BBM wire is ground when the engine is running. Havn't revved the s**t out if yet to check for 12v though lol....

Bloody thermos are still running and I can't figure out why.
I remember you had a separate post on the thermo setup - did you end up wiring it your way, or did you set it up as the EL 3 relay system ???

My way, pretty similar to EL way anyway.

I can't seem to get 12v from those two thermofan outputs though. This is being measured my sticking a pin from the multimeter between either pin 33 or 53 and ground.

From what I can see from the EL setup 33 & 53 are providing earths - 33 for cooling relays 2 & 3, 53 for cooling relay 1, so for testing, you'll need to measure between +12v and 33 & 53 in turn.
As you know, with the engine at operating temp, if you short diagnosis connector pins A & B (top left and bottom left), turn ign on, put the transmission in gear (man or auto), both fans run, don't know if this is at full speed, but if it is 33 & 53 should be both earths. Hope this gives you some ideas . . . .
