the cluster doesnt need the eec,, however the swap you've done may have interrupted the shunt wiring for the amp gauge.

go to the diy thread in misc tech ,, you will find my EVTM manual up on photo bucket.

also, double check the 3g swap in electrical tech sticky,, theres a final draft version we all did there which has 2.3L corrections as a result of someones car that caught fire because he may have made a mistake or the factory wiring had conflicts with the ref manual.

the 2.3 is a fickle ,,, and wiring is sort of a one of a kind thing.

Fixed, lol

What was that kid's name...? I think changing his own oil was a challenge, from some of his posts...

well, he seemed to have baffeled all of us with the root cause but if you read on through his thread and his details on the front end of what he did,, we all did notice an oddity with the 87 tc vs the 88 tc being slightly different. I was hoping someone who owned em all would have been able to cypher through his threads and figure out which wire took him down the wrong path.

I concluded there was an existing wiring error that by default put the 3g upgrade into jeopardy right off the bat...ie- some hacked wiring conflicting with the charge harness / shunt wiring.

The post actually started on the hopes of getting the factory speedo working. I got lost in a 3g upgrade and meeting people. I have a working alternator still no fac amp gauge or speedo can figure out the gauge just got to look at what I did wrong the gauge worked before the 3 g swap so I'm 99% sure it was operator error . Need solid answers on speedo

The gauge actually was working the whole time. the 3g alt works so much better that the gauge doesn't jump when throttling the motor like the 75 amp alt. Started the car to move in 15 degree day with weak battery and the gauge was moving then.

still no speedo Help

Read the last paragraph. I don't know much about the speedometers, or the gauges but that has a little information. Maybe you should send ericcoolcats a message, he might have some information for you.
