Outer Limits 4x4 Board

Gday,

Just wondering for those who have done the gti conversion, what you done with the speedo cable. I have read that it the instrument cluster needs some 'modification', otherwise you will get poor fuel economy... I dont really understand the idea, so if anyone could help by explaining what and why it will happen, and how to get around the problem...

Also do I use the speedo cable that came with the gti engine, or the sierra one?


Thanks

Also (save from starting another thread...)

I'm doing the GTI conversion, got my motor. I also need to know what is done with this 'reed' that the gti supposedly uses on the instrument cluster, also... what other wiring harness from the swift do i need, all i got was the engine harness from computer.
