Caterpillar Fuel X-Tender

No just the 62 pin on the MXS,NXS and the 33 pin on the other cat engines(bxs,mbn,6nz) It makes a difference on the truck where as the fuel temp wire on it already didn't make a big difference.
If I was to use a meter on the wire I removed it would goto the fuel temp?

 

I will try that aswell.
I got a bad feeling when I seen that this thing could go onto Non Acerts. Check me if I am wrong but isn't the acert the only one with retarded timing settings and the other cat engines use normal timing settings.

 

I checked it and confirmed DDS's words. the wire I hooked into goes to the fuel temp plug. I am rather pissed that he told me it adjusted the timing. but he did say that is cuts the amount of fuel down. I checked it on the ohms and it was higher than the temp fooler I had already and my truck is doing .75mpgs better on fuel. I can't figure it.
