I need some help on a trip computer install. I have the computer and have examined the service manual for the wire termination points . I understand I have two connectors to deal with under the dash. C3 at the junction block and the CCD bus terminial C-358. Here is the hard part (or at least for me) I have purchased a trip computer / OHC from ebay that must be from a different year model truck from mine, I have a 2001. 5. I can repin junction C-3 to the highline wiring to match the trip computer /OHC wiring, and I can also run the wires from C-358 CCD wire terminial. But, the computer that I recieved from E-bay has different wiring colors than my harness will have, so how do I know which wire goes where? I don't have a cross reference, and I don't want to wire something up wrong, as this could be a reciepe for disaster. I'm sure it is the correct computer and OHC, and my end will be wired correctly(harness side), but I'm skiddish about hooking the trip computer wiring up because of the color differences. And I want to add the dealer now says the wiring harness number that is supplied for the conversion, for the lower harness has been changed, to include the trip computer as well, at a cost of 340. 00 some odd dollars, that is why I am in the process of making my own, if possible. Or if somone has one thay would like to sell please contact me. Please HELP!!
