Hey everyone,

I am on the Classic forum most of the time but was hoping that you could help me. I am currently doing the EFI swap and I am trying to figure out my harness that I am attempting to modify. Basically I want to take out what I don't need. I have figured out most of the connections but there are still a few that are bewildering me. If you could lend your expertise on the 5.0 EFI engines to me it would be greatly appreciate.

Thanks,

Mike

Here are the pictures. Sorry for quality on some.

Elbow.jpg - is the vaccum connector for the FPR
balck3.jpg - looks like the connector for you EGR position sensor, but I can't be sure from that picture.

Thanks for the reply Mario. With an older Mustang do I need the EGR?

Image 3 looks like the connection for the Temp sending unit which sits right on the front of the lower intake .

Try this site:
http://www.therangerstation.com/tech_library/Wiring_harnesses.htm

Image 5: I think those are secondary air connectors.
Image 6: I think that one sends various signals to the dash along with a black connector simiilar to that one.
Image 7: I believe is the connector near the PCM that has the various fuel pump signals.

Also, I have an 89 harness in my 88 and I don't remember those white connectors in image 1. I have heard that the 90 and later harnesses have 2 white connectors for the airbags that are near the firewall grommet. Where are those connectors located in the harness?
