Theres a guy in the us that can convert the beams celica harness to plug and play into your mr2.

The only issue is, the Bathurst body loom has different pinning to any other version from the JDM or US market, and to my knowledge, there are no 100% accurate wiring diagrams around for the Bathurst. I've yet to see one at the very least. The guy who did my wiring, who specialises in auto electrical work on JDM engine swaps, hadn't ever seen one either. 
 
By the time you managed to work out what pins are where on your body loom so you could tell the guy who does the looms (mr220v), then shipping it back and forth from the USA, you may as well just get the few pins that need swapping around done here.
 
My rewiring cost about $600, which included all the repinning, as well as wiring in an HKS SLD Speed Limit Defencer Type 1 to override the speed limiter in the ECU and a Dakota Digital SGI-8D Tachometer Calibrator – which isn't required if you have the Beams gauge cluster.

Well, i've gone and done it...My Beams half cut is on its way...

I ended up getting it for US$2700 plus freight :)
 
Let the fun begin!

I noticed that an offer had been put in and was wondering if it was you. That's a really great price you got it for Rick. Well done! 
 
 

Congrats!
