Ive got the motor fired up and it runs. Ive got a few wiring problems though.
My temp on the cluster is pointed straight down to the floor, not even in the cold-hot range. I have the stock temp sending unit in the back of the passenger head.
My Tach is also not working, it is wired into the white wire behind the glove box which i believe is the tach wire.
Any suggestions/ help would be great. The truck is a 1992 k1500 and the motor is a 2004 6.0L
Thanks.
guapo, thanks for the info, ill have to pick up a resistor to see if that works.
What would cause my water temp to be so far off? the water temp sensor has only been moved to the other side of the block.
Sounds like you have it grounded instead of hooked to a temp resisitor.
how did you get your speedo to work?
well, i pulled my cluster apart because the odometer froze up a long time ago, i might have messed up the gauge. or that green plastic (circuit board)Quote:

I know theres not too many 4wd guys out there, but what is needed to connect to the 2004 4l80e tranny to make it go out of limp mode? my second connector is plugged. its the speed sensor which has the same color wires as the speed sensor on the back of my t-case.. i might splice into them and see if i get any more gears.
The second sensor for thats needed for the 4l80 is the one in your transfer case. Thats if Im reading your post right.
Yeah, i have the wires(i believe they are green and purple..cant remember) from the new harness. i just need to splice them into the wires of the sensor on the t-case. So now that the computer is getting the signal, is the signal the right pulse for the computer? also do you know what color wire is the right one to wire for the gauge?Quote:

the wire that goes to the speedo in my cluster, i know the speedo wire from the computer thats running the motor/tranny(the 2004 computer). Chilton manuals only give you a hand full of wires in the schematic.Quote:

Not sure what wire the 4k output is but is that going to be my green speedo wire from the lq4 computer? also can you explain the black tracer wire? i have a light blue/black wire from my white box.Quote:

the 4k is just how the computer reads the signal from the VSS....i dont know anything about ur truck so i cant help u with the rest..sorryQuote:

Right on thanks for the help i would see if it works but, I had to pull the motor, turns out the motor I bought has a spun bearing. So I'm currently looking for a short block or a cheap long block because I'm pretty sure the machine shop is going to charge at least 1500 bucks
Its been awhile, but the trucks been running, i ended up putting in a new lq9 and got rid of the garbage lq4 i bought. The truck runs great, pulls hard... all my gauges work besides my tach.
Ive got movement on my tach, it says it idles at 100 rpms and when im in the throttle it goes up to 1500 or so.
Right now ive got the tach wire from my new pcm to the wire to my factory tach. I got a 680ohm resistor 1/4 watt with a 12v switched power source. Anyone got any ideas of solutions? Thanks.
Out of curiosity, would your truck happen to be a 2004? NVM, just saw you have a 2004 engine/pcm. Damn, its such a pattern of issues, these damn 2004 PCMs and not able to drive a tachometer.
Well it moves, I hope I don't have to go through a hundred resistors in order to find the right oneQuote:
