I just purchased a 1998 Eldorado and want to tow a small utilitly trailer. I have a class II hitch but need a wiring harnes if one is made to custom fit. Has anyone found one or will I need a universal one that attaches to the wires with splices?

I used this one: http://www.etrailer.com/Merchant2/me...ory_Code=ELEAF (http://www.etrailer.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=E&Product_Code=18146&Category_Code=ELEAF)
but you could get away with this one I'm sure:

You can't just hook into the lights like on old school cars or you will have problems with the lighting circuits.
