Question: I have a Dana Spicer 20 T-case in a 79 CJ5. I am putting in a Painless wire kit. There is a wire for “4WD switch” which should be on the T-case. Could you tell me where on the T-case, and if it doesn’t have one, can and where would I install it along with where I would buy one? Eric J

Answer: The wiring harness from Painless is near perfect and complete. The harness includes some wiring that isn’t in some year Jeeps though. The CJ’s equipped with a Dana 20 (72-79) did not have a switch for the 4WD indicator light and no provision for installing one. The Dana 300 transfer case (80-86) did have one. Our suggestion is to tape up the wire and tuck it out of the way.
