Just waiting for a response from him I don’t wanna put my cluster back in and have to pull it all apart again
Yeah, that is what my next project is after doing the seat upholstery and carpet.
Nicely done!!!

Im happy to help, why dont you call me and im happy to go into more detail. It is a one wire hook up, the points have been disabled so the 12v stud is usless, the 5v stud is all your concerned with, unless you need to pick up 12v power from that stud for some reason you could actually cut it off and remove it, the other gauges have two studs the fuel gauge could as well once the ponts are removed. the Ivr3 ground to the case and the duel terminal is the 12v in. the single is the 5v out. simple as that,
The limiter coverts 12v to roughly 5 volts
If you only connect the 5 volt wire there is no power source to the limiter.

And that is what I thought

no kidding, your car is the 12v power source, your harness you un plugged from the cluster now goes to the dual terminal on the ivr3 limiter. you need 12v into the limiter and the limiter puts 5v out im not sure where the confusion is, Real time eng says this, I just got off the phone with Tom actually talking about this actual post. the limiter is a one wire hook up to the cluster, your car is the 12v source.

yes correct, if oyu hook up your cars harness as usual you will have 5v to the 2 other gauges, limiter..... 12v in from car same as original, 5v out to middle 5v stud, same as original, 5v stud powers the other 2 gauges as original, pretend this limiter is inside the fuel gauge and not outside,
So nothing is plugged into the 12v stud? Only the Limiter?

I am sorry so many are chiming in that dont know what they are talking about, let me explain, ive only installed hundreds over my time, the 12v wire that went to the 12v stud on the fuel gauge now goes to the double terminal on the ive3 (12v in), single terminal on the ivr3 is 5v (out) to the middle stud (5v) it says it on the back of the housing. your harness is already wired to power the oil and temp gauges from the 5v stud on the back of the fuel gauge, all you do is hook up your harness as normal, move the 12v power in 1" to the new limiter and done., the limiter does not provide 12v, it provides 5v, running a wire from the duel terminal 12v in to the 12v in stud is stupid, you disabled the points that stud is now dead internally, you simply moved the limiter from inside the fuel gauge to the outside, still needs 12v in and still puts 5v out. your cars harness G1 on the schematic is the 12v in to the dual terminal, thats all there is to it, if you have any questions call Tom at real time engineering, listen to him not everyone that thinks they know but has not installed hundreds, go right to the builder, He will tell you the exact thing. any other problems you can call me and im happy to work you through them.
