I'm relocating the seat heater switches, but need to lengthen the wires. They appear to be a 20-22 gauge. I have 18 gauge that I could use. Would it be okay to have a section of 18 gauge inbetween the stock 20-22 gauge wiring?

I would think going thinner would be a problem, but not thicker. Please advise.

 

yes that will be fine. I would suggest you solder, not crimp and also use a good heat shrink not tape.

Although it would not be a good idea to go thinner... it is more important in high draw areas to make sure you have a very good joint.

 

Thanks for the quick response. Working on it now. Doing the GT3 console delete and 997 shifter. Shifter is in, trim is off, switches are relocated, now time to cut and crimp (not a good sodderer, however good crimper).

 

+1.... the lower the gauge number means that it is bigger diameter wire.... you can go bigger, going smaller can burn the wire/insulation if the the fuse fail to blow.

 

I wouldnt crimp...... I'm telling ya.. Those seat heaters pull amps and a crimp isnt a good idea.

Yes you are right the lower the number the bigger the wire.

 

Maybe I'll soder the seat heater wiring since I did not do that yet. I did already crimp the targa top wiring along with electrical tape around the crimps.

If the crimps are good and tight, then wrapped with electrical tape, what is the cause for concern for the seat heaters? Not trying to test you, but I simply don't know. Thanks.

 

If you are just relocating the switches from the bat wing to either the slots behind the shift, or on the dash there is very little current draw on these wires, they only control relays that turn the seats on and off, and the two heat levels. The wires that really draw power for the heaters themselves are not involved. Therefore a lower gauge number is heavier wire as stated before, and the crimps for these wires should be fine.

 

They will be relocated to the empty spaces aft of the window switches. Thanks for all of the replies.
