Vehicle Wiring - American Autowire - PSI - Dakota Digital
 

Hey everyone,
So I’m working on wrapping my head around getting the wiring laid out and how to integrate the three systems together. Of course, each one states to use their wires, and their sensors in the car.

For instance, engine oil pressure, while the ECM needs that input, it also needs to have the DD sensor so that the gauges will work.

So what does everyone do for situations like this? I know that the professional shops have all this worked out, but me, a guy in his garage needs a little help.

Thanks for any help on this.

Hi Bill

I recently completed the wiring on my 67 Chevelle. I used the AAW Highway 22 kit as well as Dakota Digital gauges, and my LS Conversion used a FAST ECU. For the gauge wiring, I used all of the DD sensors/wires. The gauge package from AAW was not used at all. I believe I then used wiring from the AAW to power the gauge module. As far as the ECU wiring, I used the FAST components with their wiring.

In short, I used the specific wiring for the components of the FAST and DD, and then used AAW wire for everything else.

Hope that helps.

Thank you for getting back to me. So did the FAST need oil pressure sensor to run properly? If so, did you have to put two separate sensors?

The PSI guys are telling me to get a BMI module from DD, and plug into the OBD II port to work the gauges. This just doesn't seem like the best way to do this.

Thanks,

Bill

Use the DD BIM. Works great and is the cleanest way to go. I have used them in at least a dozen builds.

The FAST does not use an oil pressure signal, so only used the DD pressure sensor connected to their module.

100% this is the way to go.

I did the DD BIM for OBD2 and it's a quick and easy way to wire your gauges. The only negative which is minor is when you're tuning the car with your laptop plugged into the OBD2 port you don't have any working gauges. Besides fuel level in my case.

I've been trying to read about this, and look at other builds on this site. Looks like even the high end ones are using this.

I've also looking at possibly using a splitter at the OBD II. Is that something you looked into?

Thanks,
Bill

I have not tried any kind of a splitter.

Use of a splitter is hit or miss. Sometimes it works, sometimes it doesn’t.
