Alright first off, I want to thank everyone on the site. I am building my 71 C10 and have installed my first conversion Gen 3 motor. Upon asking and reviewing the posts I found all the information I needed to get the correct hardware to get the 2002 5.3 and 4l60e trans installed. I used a set of Moroso billet adapter plates with Prothane motor and transmission mounts. It should be noted that I did not have to cut or modify my chassis other than moving the stock auto trans mount forward two inches. This only required 2 new holes to be drilled. The stock truck oil pan on the motor fits perfect and only hangs down 1 inch.

However, I have now reached the critical point of what to do for a harness and ECM. I have found a couple online Chevy Thunder, Nelson Performance and Painless Wiring. Any suggestions on which one to go with. I like Nelson the best but cannot get a call back from them to purchase. Any further help would be great. I need the stand alone harness, trans harness and either a new flashed ECM or mine re flashed. Thanks for all the help guys oh and how to i post pics of the progress?

This...awesome product and support. Great price. For your set-up it is a no-brainer. They can even do the initial flash of your PCM to get it running for $50 extra with the purchase of a harness. Jon's a good guy.

I used the latter for my conversion.

Thanks guys Just talked to John over as PSI very helpful and professional I will be ordering the harness this week with one of their PCM's. Cant wait to here this thing run in that chassis. Still have to do exhaust and will be a few months before the cab and sheetmetal is back from paint. I would really like to get some pics up here to show progress and help anyone new to this with what to look for but cant figure out how to get them on the site.

Just make an account on www.photobucket.com and upload from your computer to there. Then just copy the "IMG" code and paste onto this site.

Don't know if you already have a harness or not (OEM), but if you do, I'd use these guys

Good price, excellent work. Also does Ecm edits for the basics. Everything comes labelled, including a fuseblock. I used'em. Very happy.
