Hello men,

Well, I am trying to work all the bugs out of the new ride, and as usual, I am finding more than I had hoped! So here is the latest. First of all Here is the data:

94 F250 IDIT 4X4 E40D w/ 191,000mi, With a engine rebuild and new turbo, and no idea at all of the miles on the trans, but it shifts firm but smooth. The truck is an aftermarket abomination from Centaurian, with all kinds of fancy mods which they referred to as upgrades, one of which may have been a B&M trans cooler with temp gauge. So here is the deal. The trans cooler is an aux. unit mounted near the tranny, with a manual electric fan, which seems to be working ok, except the wiring to the fan may be drawing power when off, but that is a different dragon to sleigh. here is a pic.



Right now I want to get the gauge working, so here is what I know. There is an inline temp sensor mounted on the front trans cooler line at the trans. which seems to be done properly, and is going to stay there for now. It has one wire coming from the top of the sensor which has been cut (it is yellow) more pics:




The gauge is dash mounted which is a completely moronic location, but again stays for now. (it will go in a triple pillar set up with my Banks gauges later when I swap turbos) It doesn't appear that it has ever been connected, and has four wires attached (RBYW). here are a couple pics.




So can anyone tell me how to go about wiring this gauge? I am going to do some searching for info from B&M, but you guys are usually a much better source of info, so I am throwing it out here first.

Sorry about the novel, but I always try to be as thorough as possible in my posts,

Thanks in advance,

Mac

 

For the 4 wires on the gauge
1-12 volt power
2-ground
3-sending unit
4-light for gauge
Which wire goes to what term. on gauge, I have no clue. Look on the back of the gauge, if there is a + that would be the 12 v. - would be ground, The light should be easy to figure out, so that would leave the sender for the last spot.

 

Well a google search yeilded the original B&M installation instructions, and Farmert you are correct. R is 12v power B is ground Y is sending unit and W is illumination. I will wire it up this weekend.

Thanks,

Mac.

 

hey that's nice.i have mine hooked up like this.just don't be worried about higher temp readings here.it's the highest location,so expect 10-15 degree's higher reading here than at the test port/pan.don't get freaked out if you see 220ish degree temps climbing a hill towing.you get fast responsive readings here unlike at the pan,this is why i like it so much better.you can act quicker by kicking on the fan before a sending unit can tell you from the pan when all the juice is warmed up.

this is getting exciting.soon all she'll need is out w/ that factory turbo,and in with the banks to wake her up a bit.

 

Yeah, That and maybe an intercooler! All that is going to have to wait until I get to Denver though or I won't ever leave CA! Right now I have enough work to do just fixing all the questionable wiring. Aparently the P.O. was not aware that wire is available in pieces longer than 3' lol. I think my 93 is sadly going to become a donor truck! She has a lot of parts I am going to need on the 94, as well as a brand new set of tires I could roll on in the summer time!
