Mackaussie Posted April 4, 2018 Share Posted April 4, 2018 Hi there I Can't seem to get help from anyone even Mack trucks. To find a wiring diagram for my 89 r model valueliner. I'm wanting to know where each of the 1to 14 strip connectors on Lhs of firewall are for ! There are two of them . I can trace wires but diagram would save a lot of time. Thanx in advance .

j hancock Posted April 4, 2018 Share Posted April 4, 2018 Click the pdf in the link. This is for USA models. There may be enough crossover info to be helpful? https://www.bigmacktrucks.com/tutorials/article/55-r-model-wiring-diagram/ Quote JimIt doesn't cost anything to pay attention.

The diagram you can get by the link is for early R-models. Many connections look the same there but many differences could be found with late 80's trucks.

Mackaussie Posted April 4, 2018 Author Share Posted April 4, 2018 Thanks , I've got 85 r model w/ diagram and its nothing like mine! I was tracing wires last night . Tracked most to outside cab . Can guess where coming from I suppose just being lazy and trying to save time. It would be great to know exactly where they come from. I will keep trying to work it out while hoping I can still get help with diagram. Thanx again for taking the time to look and reply appreciated.
