Wiring for Speedometer help!!

[Kros383SS]

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.

Universal Speedometer Signal Interface

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

sorry, i really didn't mean to.

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

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.

Yes i tried it with two switches. I have a brand new one allen gave me an the old one from stock. both are doing the same thing. No matter were i turn it to, it wont light up any of the gears that already don't light up.
