Ok, I've been looking for a first Gen Dodge CD. I have yet to find it written the difference between the W and D series. They look different to me.

Also, when did Dodge start using the VP44? I would like to find a pre-computerized truck if possible....just the basics. What do I look for? Years?

Any links? The answer is probably right under my nose I'm just not good at finding it.

Thanks for all your help.

w = 4x4
d = 2x4

non computer = 89-93 years

saught after = 91.5 and up because of intercooler stock.

Check out the sticky notes. they are the first post on the 1st gen forum. I believe there is a model explaination in there.

All the trucks have a rudimentary "computer". The non-intercooled trucks ('89-'91) have a black box on the firewall that runs the intake heaters/WTS light, the WIF light, and the KSB. '92 and '93 trucks have a PCM between the battery and the fender that runs all those items except the KSB. In addition it runs the charging system, and the A/C, OD, and cruise if so equipped. '91.5 trucks are the oddballs, they have a PCM like the later trucks but it does not run the charging system.

2nd gen 12 valves have a PCM that runs the same stuff as the late 1st gens.

None of the 12 valve trucks need an operating PCM to run and drive.

Thanks all for the clarifications, this will help me on my quest for the perfect truck (for me that is).

ps, Duhhh, not to hard to figure the difference between 4WD and 2WD...hahaha....I didn't just fall off something....really.

Thanks again.
