On the Holley tbi unit the {?? throtle positioning sensor??} on the left side of the unit there is a rectangle connector that has three prongs in it and my old tbi has circle connector that has 3 prongs in it and i would like to know which wires go where? I don’t want to put them in the wrong order in fear that i might break something.

The other question is on the elderbrock prefromer rmp intake for vortec heads does not have a coolant opening for the heater core and i am confused on what i should do. Njspeeder gave me a rough idea what i should do but i did not quite under stand it (sorry)

I finally got all the parts in and together and i hope to try to start it up Friday. Its been too long since i last seen it running so hopefully every thing is going to be alright!
thanks a lot every one for your help!!

 

color match the wires on the tps. blue to blue, grey to grey, and black to black.

as for keeping your heater functional. youre going to have to do some engineering on that one, and youll have to re route mostly all of the stock lines i think.

here is a pic of what i am talking about it is a circle to a triangle and i dont have the connector that goes in there so i cant just match up the wires.

 

I had to do the same thing. I used a straight 3 prong connector from my totaled 89 RS.

The stock 89 model tps connector is lettered front to rear: A B C. The front A=black, B=blue, C=gray. Hope this helps. As far as the heater lines I have mine not connected at this time. You can plug the holes and everything still works ok. If you want to connect the heater core unplug the radiator outlet and run it to one side of the heater core and run the other side of the heater core to the intake up by the t-stat housing.
