This truck I was looking at for a friend has me stumped. It is suppose to be an 04 (I believe Columbia) with a Mercedes engine in it. I for the life of me cannot locate a diagnostic port anywhere on it. I thought that there might have been one under the dash but no luck there. Am I over looking it? Is there one under the hood somewhere?
