What wire gauge
I have an idea on how to run the wires for electric seats/ heated seats but don't know what gauge of wires? I have a 30 amp circuit breaker for the electric seats and a 10 amp inline fuse for the heated seats but the same thing, I need to know what gauge for both? Thanks, Mike

Re: What wire gauge
How long is the wire? I would aim for 10 gauge or larger for anything that has a 30 amp fuse on it.

Re: What wire gauge
Thanks! Not that you made me question myself but would you run 10amp fuses on each seat for the heated seats or just one for both?

Re: What wire gauge
Depends how much the heater draws. You want fuses to be about 1.5x to 2x what you expect the circuit to draw. Might be able to look up the schematics of the vehicle the seats came out of to see how the fuses were wired.
EDIT: realize I answered for the 30 amp wire, but not the 10 amp. For 10 amps, you should be fine with 16 gauge. 14 gauge would be better though.

Re: What wire gauge
I agree with rpmerf's comments.
However, what do you plan to use as a source for seat power? If you have the stock 67-68 fuse panel, it may have been fed by a single 12-gauge wire, like my 69. So I'd definitely tie the power seat 10-gauge wire directly to the battery (through a fuse or breaker). No way do you want to run those additional amps though a 12-gauge wire and OE fuse panel.

Re: What wire gauge
I have an AAW wire harness. I was gonna use an empty hot section off the fuse panel for the electric seats..

I'd suggest you use the 30 amp circuit for the heating feature as it will more or less be a continuous duty demand.. It only takes a few seconds of current draw during the seat adjustment cycles.. Put the seat motors on 16 ga wiring and wire into a convenient "always hot" fused circuit.. Just for safety's sake, you could add an inline 10 amp fuse.. No need to go all the way back and hook directly to the battery.. If you have a distributor block, wire the heated seat circuit there using your 30 amp fuse/breaker and 12 - 14 ga. (depending on length) wire.. |
