How to: Install DIC in gmt400 overhead console

[chaingun427]

Perhaps the ecu could be reprogrammed? Or possibly swap out the sending unit board on the fuel pump? That may require the motor in the dash from the blazer. I honestly dont worry about the range. My console is actually a Frankenstein of a blazer console front end and the base and back end of my tahoe console I can provide pics later but it turned out pretty nicely

Ok.. Got a 97 k1500 and I got my DIC in tonight. Wired exactly as you have here. But for any mileage readings I get -E- Any ideas why??

I think that means you have a bad connection at either vss or serial data hookup.

Could be defective as well, check for temp, then speed first, did you connect the yellow wire on the dic to the purple on the serial data?

"E" means error.

If everything else works, likely not compatible with the data stream or the info the DIC is looking for is absent for whatever reason...

My first one showed e when I plugged it in, all fhe wiring was right I plugged in another and it works great

Temp works. When I start the truck, everything says 0.0 and then I drive a little bit and it switches to -E-. Yes we have the yellow wire to the purple wire at the OBDII port.

Hmm well try again today and see if we have anymore luck.

This wouldn't happen to be one of the DIC modules where the compass uses the external flux valve would it?

(before the stupid "flux capacitor" questions begin, read here: http://www.firstmarkaerospace.com/fluxvalves.asp)

Looks like another sensor that plugs into the DIC module. If it's not there, you would have a connection spot (IE: pins) on the DIC that has nothing plugged in.

If you need one and don't have it, the DIC won't work properly.

You also need to have a temp sensor hooked up or it won't work properly either.

Got it working. Wrong pin on one of the plugs. My direction doesn't work though.

This won't work with a 1995 right?
