    TIII to T1 Swap

    I know a few people have done the TIII to 8v swap and I am wondering what in the TIII wiring harness needs to be changed to accept the distributor and any other changes that need to be made.
    Thanks!

    Lengthen the cam and crank sensor connectors, they fit the HEP. The fuel injector connector I believe is the same as 90+ SBEC 8 valve units. You need to mod the coil pack plug for a normal coil. Other than that, just some shortening/lengthening of wires-IE TPS, IAC etc.

    TIII harnesses seem to be alot more plentiful than TIII engines!

    Its one for one, where'd all the engines go? I guess you'll have to go the hybrid route then.

    I think I know the answer to this, but I assume I would be using the T1 SBEC, right?

    Yes. You might have to move a few pins around, for the coil but not a biggie. Haven't had a good look at the wiring schematics.
