Gauge Wiring 101

[dave45090]

This may belong in the audio/electronics area but I figured I would get better response from the "FI" crowd.

I'm ready to finish wiring the following - Prosport boost and oil pressure gauges with an AEM wideband - but have a few questions.

I bought a few wire taps from AutoZone. Can I sauder the three power (constant 12v) together before wiring into the wire taps? Meaning - can three gauges pull from one source?

Dont use wire taps...Are you talking about Scotch Locks like this?

 

[dave45090]

No....it's fuse taps. I'll look for a better picture.

 

[ForceFed]

No..I know what your talking about.
You should be plenty fine ....Are they all incandescent lighting?

Your talking about these....

 

[dave45090]

Obviously on the left.

 

[ForceFed]

Yeah..THats fine..Use that.

all 3 of my gauges come off of one power source.

Thanks!

OK one more question....

Where is the best place to tap my gauge wiring into Engine ACC?

 

[ForceFed]

Well..It depends.
I haven't really dug into it..But Find out if there is an Extra slot for a fuse thats un-used and "ignition" switched.
This would be the best place as there will be nothing else on that circuit and it will come on and off with the key.
Otherwise....GO off of a circuit that is NOT essential o the engine or vehicle operation..such as a Radio circuit, CC , or something similar.
