Nelson harness length reaches inside OBS?

[gl18rider]

Any one with a Nelson harness that mounts the ECM behind the glove similar to the original on my '89? When discussing with them, they were not sure.
thanks

Why not mount it in the engine compartment? If you mount it inside the cab you then have to pass the PCM connectors through in the firewall.

My original is inside the cab. I was hoping to keep the stock look.

to do the stock look you will have to depin both connectors and drill a bigger hole to allow that. so you'd have to label every wire just so you know where to put it in the connectors...toooooo much work IMHO. i just made a bracket that holds the ECM close to the brake system on the drivers side and it doesnt go anywhere. my truck has 3300 miles on it now with no issues. if that isnt what you want then i'd just build a box to hide everything.

Instead of de-pinning everything from the connectors, couldn't I feed the cable from the inside out?

My NP harness is inside the cab on my SS... reached no problem!

Excellent. Thanks for the info.

its easy to route the wires through the firewall and have the computer behind the glove box, just make sure the harness is long enough to reach. you can cut part of the block that is screwed to the firewall that your old wires feed into the cab. you dont have to cut much to get it to fit nice and tight.
