hey dude, just a bit of info to help ya out.

the wagon is called a gf8 instead of gc8.

so your after a version 4 my98 gf8 wiring loom. (version 1-3 wont fit, same with version 5-6) from memory, with the earlier years (v1-3).. the plugs wont fit the electric doors, and with the late ones (v5-6) the plugs going into the main harness are different.

theres a few places you can try finding one if noone has one.

do a search on rexnet.com.au then put up a wanted ad.

also try these wreckers.

if you cant seem to find a wagon one.. a sedan will fit. you just have to re wire up your rear wiper and washer bottle.

hope this helps ya mate.
