Photos from my swap
It all started innocently enough in the fall of 06 - another tune-up and idle quality and cold starts are hideous with old Q-jet. After a bit of reading I came across a TBI 4.3 swap into a Jeep...

After reading and a quick trip to a local pull it your self JY
ECM / Harness /Dizzy (useless) / sensors
It took over 2 hours at JY to carefully pull this tangled mess without breaking anything in the process. The firewall grommet in this B body used epoxy like filler to keep everything together - nasty to remove.
After another 2 hours the harness was hanged like a deer for cleaning.
Removed wires and vacuum lines used by AC control circuits
Final harness, arranged and labeled
Surprisingly enough wires were in excellent shape - no breaks this was a low millage car. I did had to replaced several connectors - broken tabs and shorter overall runs. However in my next conversion I will get new harness - just to save time! Initial harness fitting:
