so over the past weekend i totaled m 99 hpt manual.... not happy at the moment. here is the good/bad- engine/trans/ecu are hopefully still good (no apparent damage to head/block but powersteering pump/alternator are mangled), yet wiring harness leading to the ecu is torn/cut... so im looking for a 99 s/c70 glt/t5 with blown something and swap the entire driveline/ecu

questions i have are the following? since i cant salvage the entire manual wiring harness, how much more difficult would it be to get the manual ecu/driveline to work with the auto harness? i looked at the manual harness and it is only damaged where the passenger headlight used to sit, is it possible that the harness disconnected somewhere on the way to the trans?

OR would it be easier to locate a 98 MY given the less electrical complexities and block off the VVT, yet i dont have a 98 manual ecu

OR (im guessing this wont be easy) get a 99 N/A manual s70 and swap the engine/ecu - is the wiring harness different between turbo/nonturbo? dont want to go this route do to the turbo plumbing, would need to buy new parts since my front end is completely gone

if i do through with, i want it to be done right as if it was a factory job, and i dont need to rush as i am driving around in a NA s80 for the next few months (its way to slow)

I'm in the same boat: http://forums.swedespeed.com/showthread.php?179954-Deja-Vu

There are two ways to go about it, one is extract and repair your harness, if your ECU is still good then you're halfway there. I believe the plugs are the same so you'll just have to copy the wiring, and you can possibly start with an auto harness, you just might have to add in or move some of the wires. That or get really lucky and find a 99 manual x70 that you can buy the wiring harness out of.

The other way is to just buy a replacement car with auto and swap the tranny, and pay for a tune that reprograms the auto ECU to not throw codes or rev limit with the TCU missing. The only negative to this is that you lose the cruise control. I'm going to talk about that with Lucky when I buy my new tune but as far as I know there's no way to fool the car into making it work once the auto trans is out.

Here's my last manual swap thread: http://forums.swedespeed.com/showthread.php?107895-I-m-putting-a-manual-transmission-into-my-C70

And here's one where a guy did a lot of experimenting with ecus and wiring: http://forums.swedespeed.com/showth...-Conversion-Update&highlight=c70+transmission
