AAN v's ABY

[Tonks4x4]

I have been asked to do an AAN convertion into a 90 Saloon.

A few questions if anyone can help.

1. Can the AAN ecu run on an ABY loom and visa versa.
2. If that's the case I take it that it is easier to use the ABY loom instead of the AAN one.

yes they can run vice versa unless you have an immo ecu going onto a non immo loom,not sure if the coil reader can be added to an earlier loom or not?.

aby loom will make the job easier,the AAN doesn't have the nice fuse box plugs on like the ABY loom but i know of several people who have used the AAN with success.I was originally going to use an AAN loom on my 90 but have decided i will use the ABY.I've had them both side to side a few times and the ABY is a lot neater imo.

Is it a B3 90?

How will I know if it is an immobiliser ECU? Part No: 4A0 907 551 C
Yes it is going into a B3 90
and do you have any details on how they spliced the AAN to fusebox area if I can't find an ABY harness?

if you pm me your email address i will send you the wiring diagrams if you want,theres only 3 or 4 cables that need juice


i will have a look into that ecu part number tomorrow

[spink]

that ecu part number is an S6 AAN ecu,as far as i know all S6's were immo

I can UNimmo that ECU no probs... and a wee chip upgrade too of course. PM me if interested.
