Got the TPI mocked up on the old 283 block. I mounted a coffee can where I will be cutting a hole in the floor to bring in the computer wires.

Next question: I have an old pigtail I want to use but the colors are wrong.Does any one know where the pink wire from the coil  should go? To the yellow on the right or to the black on the left???



Thanks

Got the computer mounted behind the glove box. I made an aluminum plate and screwed it to the plastic heater box. I cut out a hole in the passenger side floor as high up as I could get and checked the fit. The wires were just long enough. ;)

1992. I've got the wiring diagram but I'm not sure about how to figure out which should be pink and which should be white.

You've got two connectors . One has 2 pins and the other has four pins correct?

Small connector Cavity A is white Tach Signal
Cavity B is pink. B goes to the ignition switch B+

The 4 pin connector goes to the ECM and is
A BLACK/RED                     D9 @ECM
B TAN OR TAN/BLACK          C7 @ECM
C PURPLE/WHITE                D8 @ECM
D WHITE                           C8 @ECM

Thanks Vile. Yes I have a 2 and 4 pin connector. The 4 pin connector I have no issues with. I was missing the complete 2 pin harness. I could only find the coil end to buy as replacement and I found an end to fit the module in my parts stock.Only still one problem. If you look at the photo above where the pigtail goes into the module, I checked and there are no letters on the module. Should I assume "A" would be on the left and hookup the white to the black and "B" would be on the right and hookup the pink to the yellow?

EDIT: I found this drwg. It appears that the pink would go on the left and white would go on the right.

Anyone see a problem with using brass compression fittings for the fuel in and return? Seems like an easy way to fix the lines that were cut when I got the TPI unit. I have high pressure line and clamps and will be using only short pieces as needed.

I read somewhere that the 5/16 return line can use regular fuel line. Thoughts?

Got the wiring for the coil and distributor done.




Made up a couple of mirror stainless steel covers this morning at work for the coil and MAP sensor and got them screwed on.
