Re: 72 GMC Longbed Duramax Swap

I pulled out a lot of wires that I knew definitely I wouldn't need. The ECM connectors are easy to remove pins so the hard parts is removing all the wire loom and tape.

The thing I wish I would have done was to go ahead and figure out where my ECM and TCM were going to mount and route my wires accordingly. I knew where I wanted to mount them but it didn't work out so things got a little messy at the end. I also left some wires that I wasn't sure I was going to use like MIL, cruise, and stuff like that would have made it a cleaner install if I would have removed since now they are just tied up in the loom.

I'll have to look to see if there any differences between the LLY and LB7. Let me know if you have any more questions.
