87 TBI to 69C10

[northerngt]

Good evening folks. I joined this group in order to help out my brother who is working on installing an 87 TBI 350 out of a suburban into a 69 C10. While researching this on his behalf, he has no computer or the skills to use one if he did, I've read that there are just 4 wires that need hooking up to the 69. Another place said there are 11 wires. Is there schematics that show how to do this and what wires go where. Go easy on us as we are bodymen, not electricians. Thanks in advance.

Most likely the TBI Engine Control Module (ECM) is part number 1227747? Please verify the ECM is 1227747.:thumbsup:

Factory 1227747 schematics are posted in this thread: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?304-1227747-ECM-Information-42

The ECM needs Battery + / Battery -, Ignition Switch power when the ignition key is in both the On & Start position.
WARNING, DO NOT USE THE RESISTOR WIRE FROM THE 69 C10 for power!!!!!!!!!!!!!!!!!!!!!!
