EEC-IV Scanner Plug Location?

[Madracingalley]

I have a 94 Xlt Supercab 4L 5-speed 2WD and I'm up to 165,500miles and I believe someone pulled the check Engine light because It never comes on...So I would like to at least know WHERE IN THE HECK this EEC-IV connector is so i can try to pull the thousands of code my truck probibly has... (If it's under the drivers side of the dashboard then I must be blind cause i don't see it)

There is a MODIS scanner at my school and was wondering if there was any way to hook it up to that.

check under the hood on the drivers side, in front of the firewall. If I remember correctly, that's where it was on my grandpas B3000.

It may be on the passenger side, but either way, it's under the hood, not the dash.

Under the hood, mounted to the driver's side wheel well, aft of the fuse/relay box.

Check the Tech Library here on this site for a simple proceedure for pulling and reading the codes.

I dont know how your truck is set up, but mine was passenger side, above front wheel well, right behind the fuse box. IF YOU DO A CEL TEST, use a length of wire and attach the signal input (i belive its called, it's the alone one off to the side) To the negative battery terminal.

that's where my '90 is. I think they moved it to drivers side for 3rd gen.
