ok took my msd 6a off my 93 TA to use on my winter beater and cant figure out the four wires that have been disconnected and are part of the car. I tried checking in the hanes manuel and that was a dead end. I think the red and white go into the coil from the computer. but where do the black and orange ones go that come out of it (the coil)? Any input or running out to your car to check would leave me in your debt. Thanks

 

Did you try checking out the wiring diagrams on MSDs web site?

 

I just checked and it just shows how to wire up a msd box not how to re wire your car after you take one out. Thanks though

 

Sorry, I read through your post too fast. i have this diagram from a 1995, but it seems the wire colors are different for your 1993. Might help, though.
