Can someone who has an '87 F150 tell me if this year and model has a check engine light on the dash. Mine doesn't and I'm wondering if it is burnt out, disconnected, or doesn't exist. Thanks.

 

I think they do not exist on an 87. Mine doesn't have a bulb in that location in the dash, and when I put one in there, it never comes on.

 

Thanks. I thought someone else said that in a post I read a while back, but wasn't sure.

I tried to pull the dash apart to check the bulb, but couldn't get the **** for the headlights off, and didn't want to break it, so I gave up.

I wonder if a check engine light can be wired in somehow?

 

I'm sure it can be. The output wire is there on the computer, it just doesn't go to the dash. It goes straight to the self-test output harness, although my wiring diagram says there's a splice that goes to the instrument cluster. A light bulb on top of the dash would probably be easier than trying to get the correct spot in the cluster working.

 

It's not difficult to add the terminals to the back of the cluster - I added a BUNCH to mine:

If you look at the back lip of the ****, you can find a notch. Put a hook probe in there to depress the clip, and the **** will slide off the shaft.

If you can get your hand inside the dash to reach it, there's a button on the back of the headlight switch. With the **** pulled out, press the button and the shaft will come out of the switch. It just pushes back in.

 

So I guess I'll try Steve's suggestions to get the dash apart and see if there is a light there. If not, I guess then I'll splice into the self-test wire harness and connect a light bulb. I'll let you guys know how it turns out.

Thanks.
