I just purchased a new 2004 Ford F150 Supercab, XTS, 4.6L pickup. A quick look under the hood and I noticed a main wiring harness to the computer was laying on the back corner of the valve cover. I expressed my concern to the dealership and they talked to their shop guys who said it's fine, "only the manifold gets hot enough to do any damage to the cables". The wiring harness has a connection tab strapped to it and there is a stud on the firewall just sitting there doing nothing. If you pushed the harness back a little it looks like it could easily fit onto that stud. I pointed this out to the dealer and they still insist it's fine where it is. I'm sure the protective covering on the harness will last the 3 years /
36,00 miles warranty but I'm hoping to get a longer life span than that before having electrical problems. If you have a 2004 Ford F150 4.6L engine please take a look at this cable harness and tell me if yours is connected to the firewall or resting on the valve cover... I appreciate your response.
Thanks, Rick
Cable details: The computer is located on the right side of the vehicle on the firewall with three large wiring harnesses connected to it. The harness I'm referring to is the outside connector, the one closest to the fender.
