I just need to get the dakota digital tach integrator, and put some 3.73's in it, My speedo is set for 3.73's, I am running 2.73's so its way off. I ended up using a 3rd gen gauge and soldering "jumper" wires on the back of the circuit board to send the actual gauge its 12v, ground and resistance wire. So I knew it was getting the actual signal, not a signal going through resistors and such. The only problem is that the back light on the odo only comes on when I turn on the lights. But Im not too worried about it right now.

If anyone has questions about the 98 cluster let me know, and I will try and help.

 

Use a digital cluster from a 97 wont need any mods.

 

how did you get the fuel gauge to read right?

 

Its easy as pie man! If you are up to the task. You take the front/rear cover off the cluster. Remove the gas gauge needle. Now you must remove the round assembly that controls the gauge. Pretty easy and straight forward just by looking I do have some pics but will have to dig them up. Now you will need a older fuel gauge assembly. Rule of thumb if it threads in it dont need a computer signal to run it. You cannot use a thirdgen gas gauge because it does not rotate the right way. A 2nd gen t/a gauge will work but is a bit larger and will need a touch of trimming. Bascily an GM gauge from a older car that dosen't require that pesky signal from the ECM, the gauge you find must defelect from left to right. I can go into further detail but don't have time at the moment. But its about an hour from start to finish and straight forward once you get all the parts.

97 models work fine. The info I posted is for 98-02

 

i have many old fuel sender guages laying around from various old gm vehicles, should still have one from the 79 t/a too somewhere around here




good luck

 

see thats about what i tryed first time around but i tryed the the lt1 sender and got nothing.
