Key fob?

[Bowtiedtahoe]

I bought my truck knowing it has no key fob with it.
It's a 97 tahoe and I've tried programming the new key fob I bought for it.
My problem is when I put the jumper lead from #4 to #8 it never recognizes the program mode ( by locking and unlocking the doors. )
So what am I doing wrong or what should I do?

use a test light or dmm and test the #8 white/black wire to ground on the dlc connector.does it light up or do you see voltage? if not check for constant battery power on orange wire on keyless entry module and power on the pink when ignition is on.

Did you ever figure this out?

I would like to add it to my writeup if so.
