99 Chevy 1500 & 2003 Chevy Blazer

OK Folks. hope you can help me a bit. Gave my friend 2 car starters for x-mas. The first was installed in his 99 Chevy pickup. this is a stripped down, basic, no power anything. It will start and quit. I assume I need the bypass module. I read in other posts about using resisters also. What would be the best way to do this. he has 200,000 miles on it and uses it as a work truck only. He really doen't want to spend much on it.

Next vehicle is the 2003 Blazer. This is his wifes truck. I didn't start the install once we had the issue with the P/U. The blazer does have power locks and also remote entry. The vendor I order stuff from has a DEI-457GW. Is this what I need for this truck ?

I've done a dozen of these starters on Fords and Jeeps, and finally hit the problem ones. Hope you can help.

Thanks, Guess I'll order it in the morning.
