Fitting the engine harness plug through the firewall.

[fitz]

I'm in the process of stripping a rusty M1008 for parts.
I have all of the plugs on the underdash wiring harness unplugged. I can't get the plug that connects to the engine wiring harness to fit through the firewall. I pushed the grommet into the cab, the plug just seems to big for the firewall hole.
It's the plug just to the left of the glow plug resistor (as shown in the picture).
I searched, but didn't come up with anything. I must be overlooking something.
Thanks .

It will fit. It is the diagnostic connector? Every one of the plugs fits thru the respective hole they are assigned. They are tight and an exact fit.

It fits thru from the engine side. You must push the engine side connection thru the hole in the firewall after you push the grommet thru. Outside to inside to get it out. Good Luck.

Thank you.
I pushed the grommet from the engine compartment into the cab. When I seen that the plug was a tight fit, I figured I'd check and get a second opinion. Its been a long day, I didn't want to force it and break it. I'll have at it some night this week and get the harness out.
Thanks again.

Use some "silicone" spray to lube up the wires and the grommet.

The plug came right out for me tonight.
At least I didn't ask how to change the spark plugs.
Thanks guys.
