      Is 18 gauge wire satisfactory for constructing this harness?
      Old, not obsolete.

        More than enough.
        Try to use TXL instead of GXL or SXL.

          Thanks.

          I have enough 18g TXL left from my electric fan project to get this done.

          Mostly I was concerned with it being sized correctly for the OE connectors. A little googling indicates the connectors accommodate wire with a cross section of between 0.5mm and 1.0 mm. 18g falls right in there. I was just too lazy to look for myself and figured the hive mind would know.

            Complete derail, but you wired a fan with 18AWG? Bit small ain't it?

              Fair question. The 18g was for the fan controller. For the fan itself I used 10g.
