yj 350 swap aftermarket speedometer
 
I have a 94 yj and im in the middle of a 350 swap. All I have left is to wire up the gauges. I'm going with aftermarket auto meter. Does anyone know how to wire up the speedometer? There's 3 wires going to the sending unit. Orange‚ white & orange and blue & black. They all run to the ECM plug‚ I'm not using the ecm. And the orange & white wire also runs to the gauge cluster plug. Does anyone know how to make it work?

What kind of VSS do you have electronic or mechanical? Are you running efi that will need a VSS input? If you have a electronic VSS do you know the Pulse Per Revolution?

From the VSS:

Orange is 8v supply from the ECU.
Black w/ blue strip is ground.
Orange w/ white stripe is signal wire back to ECU and the speedo.

You can wire the orange w/ stripe directly to the speedo and 12v from a switched power source to the orange and the speedo will work correctly.

I'm going to save you a whole lot of time and frustration. Seriously take a look at the newer GPS speedos. If you have already purchased an electronic Autometer speedo, there is a new GPS module that just hooks up to the guage. http://www.autometer.com/cat_accesso...l.aspx?vid=234

Took me about 10 minutes to install mine and I'm not a fan of anything electrical.

Might cost a bit more, but its the easy button.

That is pretty cool. Because I had a 40 tooth tone ring and my ECM wanted to see a 4PPR I had to buy a Dakota sgi-5. Then I set the autometer gauge to 4000PPM (ECM output to gauge).

Thats basically what I was facing too. This seemed like a no-brainer. They are apparently getting quite popular with the muscle car crowd as well. When I bought mine, they had sold 4 others that morning. Good product.
