Wiring for Speedometer help!!

[NITROUS]

Ok, that cluster uses a 2000K pulse and the LS1 4L60E uses a 4000K Pulse. You'll either have to install a dual reluctor ring on the tranny tailshaft like S&P sells for $500.00 or use a Dakota Digital Signal interface with 2000k pulse like this.

I did it on my buddy's 89 model when we put the LT1 in it. It's been so long ago that I can't remember how we did it though. It can be done.

Is the 80ea 4k pulse output also. When I ordered my tune I told them I need the speedo output to be for my stock gauges

Man I sure would like to know how ya'll did it!

I was thinking about doing something like this:




The thing is I don't know if soldering extra wires onto the original VSS wires will foul up the signal or not.

The LS1 or truck PCM doesn't put out 2000k so you'll either have to use the DD interface, install dual reluctor rings or mod the PCM which I think there's a DIY forum on Thirdgen.

Man ur raining on my parade with this bad news!!

I'll just stick with that DD interface, appreciate the help!

Ok I was just on DD site reading up on that interface unit and it says the 700r4 output 4kppm, so is it then coverted to 2kppm for the speedo? Im a little confused bear with me!

so what does my 4l80 output(its a 93 model)??s

[ChevyLee]

sorry, i really didn't mean to.

[NITROUS]

Yes it converts the signal to 2000k. Call and talk to technical or sales, they were the ones that told me it would work.

[NITROUS]

Damn that sucks ChevyLee, maybe the switch is bad. Do you have another one? I'll look in the garage but I think my original one was broke.
