zowzvvhf Posted December 24, 2015 Share Posted December 24, 2015 Hi,New to the forum and trucks. A friend has a 1984 Mack Truck RW613. My apologies if my nomenclature is wrong, but this was what I could grab from the plate on the driver's side door. He's looking for what he calls the wiring harness and I am unable to grab a specific part number or find much on it. If you lift the hood up, and are looking at it from the front, it's on the top-right side (driver's side) of the engine where all of the wiring comes in and looks like a standard relay block. Does anyone know where to source this part or a specific number?Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/43249-wiring-harness-for-an-84-rw613/ Share on other sites More sharing options...
thomastractorsvc Posted December 24, 2015 Share Posted December 24, 2015 Are you looking for the terminal block or the wires that go to the cab, go to the rear, or go to the hood? 1 Quote Robert"I reject your reality and substitute my own."

zowzvvhf Posted December 26, 2015 Author Share Posted December 26, 2015 Are you looking for the terminal block or the wires that go to the cab, go to the rear, or go to the hood?Terminal block is my understanding. Do you know it's part #? Quote Link to comment https://www.bigmacktrucks.com/topic/43249-wiring-harness-for-an-84-rw613/#findComment-317424 Share on other sites More sharing options...
thomastractorsvc Posted December 26, 2015 Share Posted December 26, 2015 Call your local Mack Dealer or Watts Mack (site sponsor) and give them the Vin and they can tell you a price and part number, if it is really expensive you can google part# and search it. Not sure where you are located but PM "Superdog" or SparrTruck or radwillg anyone of them should be able to get a good used one. You could also count the terminal studs and find something on ebay or other internet store. I have replaced a few of the smaller ones with some terminal blocks I got off line and locally at the truck parts store. Quote Robert"I reject your reality and substitute my own."

zowzvvhf Posted January 4, 2016 Author Share Posted January 4, 2016 Yeah, I got a quote of $25 from a local dealer. Turns out, they want both sides of the harness, which brought the quote to $1400. I could not find those anywhere online, though.
