I have a 99 Jeep Cherokee it's my yard car it's basically just a 4 wheel drive play toy and I'm having issues with the wiring in the computer and I don't wanna put any real money into it but I wanna play with it or how can I get rid of the computer or is there any way I can use a different one I just don't wanna Chase a bunch of wiring issues when I know it's got them because it sits and its old.
