Sourcing parts for OEM ECU setup
christim - 7/3/21 at 10:24 PM

I got the engine turning over the other day, one step closer to firing up. So now thinking about the electrics for that...

I've got all the 1999 blacktop Mondeo loom back to the 42 pin plug with a matching ECU and key, and the entire Sierra loom. Reading Big-wasa's excellent thread on OEM ECU it looks like I'm going to need the immobiliser led and wiring plug for the immobiliser tranceiver.

Quick trawl online isn't bringing too much up...any thoughts on where to get these?

The PATS transponder sits around the key barrel under the steering wheel cowling.
The good news is they’re not coded so can use any from the same generation engine.

You can use any standard LED, you won’t need the one from the car.

Easiest way will just be to find someone breaking a car.

Cheers I've got the transponder itself just not the wiring plug for it (worst case will be I just wire each pinout to a suitable connector)

I’ve needed a few extra bits for my zetec conversion, again I just find someone breaking a car and ask them to post the chopped off wire with the connector, probably worth a look online!

I might have a spare plug. But it's probably going to be next weekend before I can get in there and look

Aah cheers Wasa if you do! Otherwise yep I'll look to find someone breaking, or crack out the soldering iron
