nobody knows if i can run the easy 4pulse adapter????
Looks simple enuff. What's the difference b/t the stock VSS vs that one? If stock is 4-pulse setup, take it and run. All the adapter does is report electronically what it sees to the PCM, with a mechanical output to the speedo, right?

If you call a Chevy dealer, and they don't have that info, call a GMC dealer. The two brands in my area have different catalogs. The Chevy guys have more info in their system. I'll check AllData to see if anything's listed (doubt it though).Quote:

I'll have to build a skid plate for it...but that's cool...

why do you need a speed sensor??? wont the engine run without it?? can it be programed out?? check
street&preformance
advanceadapters
if your looking for just a speed sensor to tell the computer that the car is moving i dont think it matters how many pulses it is, as long as it thinks it is moving. my 350 tbi flat fender doesnt have a speed sensor input. it runs just fine, pluss untill the computer sees speed input it wont look for egr or do emmission testing. i dont have a custom chip or any emmissions wired up and have never had a check engine light come on yet. people say that is is not up to full power untill it senses speed but i cant tell it runs dam good.
