ODBI or ODBII

I had to hook up 4 wires in the engine compartment to run my OBDII system on my '68 with a junkyard 2000 5.9 Magnum and a 727 for a small block. It was plug and play, because I used the hotrod version for this motor from Hotwire Auto. The notch for the bellhousing to clear the crank position sensor is best accomplished using a plug cutout with the little drill bit in the center, similar to what they use to cut the holes for the doorknob on a door.

I used an ECM out of a 5 speed 3/4 ton truck from Solo Electronics with a lifetime warranty and then flashed it with an SCT Tuner from HemiFever.

It was my first foray into EFI and I learned a lot. There are several cool ways to go with the fuel system these days.

I'll never go back to a carb on this car. It's in the final stages of a drive train upgrade, and I already had the new base tune emailed to me to download into the ECM. I don't use a computer on my automatic overdrive transmissions.
