AFAIK the 4 plug possum link pinout is the same as the V3/4 WRX. Covered briefly here:

Cheers "gotasuby" arrr I took a link wiring loom out ov a conversion leggy and I remember that one of the plugs which usually full of wires only had mb 4-5? I'll take sm pics ov it see what u think '-)

[thrashr72]

Arrr help so untecho lol how to upload pics of ecu in an attempt to find out which link I have and to get correct pinouts... ta

You need to sign into an image hosting site like "photobucket"and upload your pics there. Then copy the link that it'll give you and paste it here to post an image. The link will have "img" tags or start with "url=".

Here's a comparison of the 4 plug ecu's that I've managed to chase all the pins over the years. The bd5a/bg5a pinout is completely different to the normal wrx or bc5 pinout. So you'd have to know whether your possumlink was originally intended for the normal layout or for the bd5a layout? I didn't think that they made a possumlink for the twin turbo, 4 plug legacy?

[thrashr72]

Thank u will try now... and yea the link loom I took ... on one of the plugs only had 4-6 wires instead if the usual full compliment lol wish I'd kept better care of loom now haha

Hey ya Ross... know which link ecu this is and exact pinouts? By chance lol http://s112.photobucket.com/user/heelers_dotcom/library/Mobile%20Uploads and new to navigating phone on CS so unsure how to pm u :-) well arrr anyone actually hehe

[Koom]

Here's all your pics. You just need to click on the share link icon, then select the link to paste here.

Although I can't tell which setup that possumlink would be from the pics.

What is this "loom"that you have? Is it an adapter from the ecu to the plugs in the car?
