Here are all of the various part numbers and specs from the 1968 Factory Parts Book. You will want to look at all of the (W) applications on the second page (page 16-2) below for your Coronet R/T.

Hello Ron,

Thank you and you're in luck my friend, because I just purchased copies of the 1968, 1969 and 1970 Factory Service Manuals in a CD format, so I will be adding all of the 1968 and 1970 Coronet wiring diagrams in the next few days to my wiring diagram thread that is located in the "Tech Archives" forum and the 1966, 1967 and 1969 diagrams are already in place there. You should be able to make copies of those 1968 diagrams for your car soon so that you can take them out to your car while you're working on it.

I'm also planning on adding the 1965, 1971, 1972, 1973 and 1974 wiring diagrams in the future as I'm able to purchase those model year service manuals.

Richard

Thanks Richard, Very Generous of you !!!

There are so many fantastic folks here on the DCR that I have to do something to earn my keep here Ron!

By the way, I REALLY like your 68! Before I found my 66 back in 1989, I would have loved to have found a nice 68 but you just don't see many of them here in my area.

Richard

Thank's for the Faxon Link; Very good Info; I'll use them my future need's; Thank's again Richard
