Short version....
Moates Autoprom, G2 adapter, 27sf512 chip(s) for a 7427 PCM.
Wanting to burn a spare chip or 2, one w/o 4L80e settings, one (maybe 2nd for a spare later) with.
Will it hurt...

I am converting my dizzy to a 7 pin module and cant find a factory style connector for the 5 pin side of it.
I know I could use small female spade connectors, but I would really prefer one like...
Just started my TBI for the first time, it runs:happy:.
Had me frustrated because the fuel pump was working at key on, then I plugged in my autoprom and ALDL cable and no fuel pump.:mad1:
...
If anybody has a pinout chart for the ALDL I wouldnt mind seeing that also. I know which is ground and ......................
Never mind just found it in a shop manual.

I had to clip some wires to get this harness out last summer and now dont remember what these two go to.
Would be G, and H on the ALDL. Red and white respectively.
What are they?
My best guess...
Bringing this thread back up with a question.
in the pin out chart on page 1 it lists.................................
Why not brake switch?
I had planned to swap in the cruise as well...
Ug, more to figure out. I should have dug up all my parts from one vehicle. But so far I'm only out $50, because most of it was free.
Harness and tbi from a 91 C1500
Pcm from a 95 p30 van

I thought I had a 96 4L80e, but now am finding out its a 91-93 early version. Is there any reason it wont work with my PCM, or anything I would need to change to make it work?
Thanks,
Jim
OK which was for the 4L60 ? post #4 ?
Just got the plugs out of my trans and inside for a better look. Its older than I thought, has the 91-93 style plug. I nned to figure out if this is going to...
Saw a few cool ones while doing some practice stuff in 7747 ecm's $42
I really like this one

Just wish it had trans temp...
Just practicing to get familiar with where things are and how they work in TP.
But yea, that buffer end value changing itself sucks.
Tomorrow more practice. I am off till tuesday, and plan to...
Yep, Yep, and Yes sir :thumbsup:
All good now. So, I guess it was only partly me.
Maybe tommorow I'll take it down and plug into my DD and see if I can data log something.
Thanks for your...
That look right?
If so, the only question is why it wont verify?
Thanks for bearing with here,
Jim
It does say
"PROM I/O succeeded"
if I hit "Read chip" now though.
Well buffer end was showing OO7FFF
Fixed that but now
"FAILURE: Verification failed (not matched)
Long version........
Trying to familiarize myself with the new equipment.
So I got my AutoProm all hooked up inside where its WARM (freezing out by the way), tunerpro rt going.
Pulled the eprom...
Hmm, ok, I took it to mean it was letters cast in. Thanks for the clarification.
Still, 12 pins and both cooler lines up front means either 95 or 96 from what I have seen.
Everything I have found...
OK, I got the 12 pin connector, but no "PWM" casting ANYWHERE that I can find. Anyway, by the above that means '95^ so my tranny guy (automotive, not THAT, get mind out of the gutter:nono:) should be...
I'll have to make sure my transmission guy knows what computer I am running. Sounds like my rebuild may have just gotten more expensive. Great.

Hmmmm, read the last post here .....................

Thanks, that should help.
Not sure what differences there are with the transmissions. I believe the one I have is a 96, hopefully that dont cause me any issues. Price was right though, straight...
I have found several pin-out lists/diagrams for the 7427, but most of the 4L80 wiring stuff is not there.
Anybody have a chart for these?
Thanks,
Jim
I'd be curious to hear more about this and how it works........
One setting for cruising, and another labeled "GET IT!!".
Doesn't really apply for what I am doing, but still interesting.

Just checking to see if my sig is working now,
and it is.
Hello, Jim here. Been lurking for a couple days, trying to get my head around all the things you guys could teach me. Not sure I am smart enough to understand it all, but I'll catch on eventually.
