1970

I am doing a LS into a 1970 Chevelle and want cruise control.

What do I need?

I used the gm cruise module that was on the donor car and the wiring diagram in the swap stickies. Works great

If you have drive by cable, then these factory modules work way better than the aftermarket in my opinion. I have a Dakota Digital on my Nova, and a factory module from an Astro van on my '33. The factory one works like, well, factory! And they're cheaper, I have about $50 tops in mine, getting parts at the pick a part. The DD just isn't as smooth and precise, and I spent almost $200 on it.

If you have DBW, then you're almost there anyway, just hook up a few wires to a switch.

I have one of each.

Which should I keep?

TH350 transmission

DBW ie easy to hook up cruise if you have the correct VSS setup. I'm assuming your th350 does not have a VSS and reluctor. The dakota digital pass thru does not provide enough pulses per mile to get the factory CC to work. I'm currently adding a VSS to a T10 sensing off the 39 tooth reverese gear for CC to work with DBW. Check with Brandon over at LT1swap.com, he did something similar with a th350.
Otherwise, the factory system with cable TB will work, if you got it off the donor car.

At some point ( I believe 2007) factory moved some electronics around and requires BCM for cruise. That means that aftermarket cruise is required as no one integrates BCM in harness. How do I know... I got a l92 from 2007 escalade and all my research indicate that I can not make factory cruise work. I got my harness from speartech and John said that there is no way (at this time) to get factory cruise to work.
Food for thought when you select your motor.

One possible solution.
