Pin 21, its white with silver stripes on it.

Pull the 3rd plug out (blue), bottom one on the ECU, and look to the 3rd row down from the top. Its on there.

I would suggest using pin 24 as the earth and pin 25 for the 12v feed.

Is this the same for MY99 UK?

Yep, MY99 and MY00 ECU's are pin compatible.

What is the correct signal wire for AFR gauge on WRX MY94 (Wagon)

Think it was said to be wire 7 but forgot which block that is in. What colour and where to find it would be great please.

Thanks

At the risk of asking a silly question how do you know which number pin is which. I guess I can work it out from the above but I'm doing this at the weekend and just want to be sure.

If you look closely at where the wires terminate in each plug, they're numbered. You can work it out easily enough though. Top row as you look at it from right to left is 1 to 9, second row is 10 to 18, third row is 19 to 25 (with a gap of 2 in the middle), and fourth row is 26 to 32 (again, with a gap of 2 in the middle). So in the case of the AE802, it's the third row, third in from the right...

Late responding, but I was just quoting.

Where exactly is the ECU located in an MY99 UK Wagon?

Thanks for the help.

Beneath the front passenger carpet. Pictures below should help...

Thanks, The_Judge

Unfortunately the above info doesn't help me!

Have the ECU out, and have fitted / wired in the AFR all apart from the ECU wire.

My ECU is a V9 type, MY94 WRX wagon, and has 4 plastic connectors into the ECU, 2 large on the outsides, 2 smaller between those.


So, once again, any one know the RIGHT wire for a MY94 JDM model, V9 ECU ?

Thanks


I really need to rebuild the car so quite urgent!

Cheers Bob, was a bit lost there when my ECU plugs didn't look anything like the diagram on another link on here!
