Tapping a TPS and RPM signal

Not certain this is right section so please move if its not mods.
I have my car info in the introduction section but to sum up, its a 94 cavalier, a 3800sc out of a '00 buick, a 94 olds 88 pcm, and some combination of them in the wiring harness. Either way, the cars currently obd1 which makes tuning more complicated. I bought Zeitronix ZT-2 for data logging and trying to wire it in right now. I tapped into the white wire on the ICM (E -Pin) which I found in an online schematic. Unfortunately I am not getting any voltage from that wire. So now I'm stuck as to where else i would tap into and get a quality signal?

Next is the throttle reading. Where would i tap into for that? Right off the sensor? Which wire?

Hoping to get the logs needed tomorrow so i can have my pcm tuned and stay out of the lean issues I'm having right now.

Any help is greatly appreciated

WHen I had "OBD1" vehicals, I used WIN-ALDL for data logging, it workerd great, and is free. All instructions, from building the OBD-1 cable, to using the program can be found on the net.
 
I bought a moates cable but it appears when they did this swap they never hooked up that port.. So im stuck with zeitronix. Just need rpm to work so I can get this puppy tuned.
