Well its been awhile, not sure if any of you remember me but im looking for the electrical harness that connects the optispark the the PCM. The harness that connects on one end to the opti and the other end connects up beside the intake manifold. I also need the 3 bolts that secure the opti to the block/timing cover. Just PM me with offers or any info. It needs to be from a 93 or 94 lt1 to work.

 

Better off to get a new one from MSD. They will eliminate the problems experienced with the GM part.

 

i dont think you can buy that seperately, i would also go for the MSD unit, i just had it installed in my camaro and its incredible and well worth the $500, it idles and shifts smoothly

 

I might have something but dont quote me on it. Ill have a more serious look around if you really cant find them anywhere else.

 

i saw the opti wiring harnesses on ebay recently... and the bolts are either a dealer item or maybe you can find them at a hardware store...

according to the bolt/torque specs listed at http://shbox.com/ci/fastener_matrix.html, they are 1/4"-20 x 2.75"

 

MSD=Crap! Mine cost me a year in downtime and alot of money, it has been the root for all my problems and not worth the $500 i spent on it. It is being sent back this week, i put my old one on and my car was fine so i would not recommend it to anyone!
