Exhaust downpipe supports built to sit in the factory 5.0 hanger
Parts removed and ready for final welding
Holley provided 02 sensor wiy bung also in place, requires drilling a 7/8” hole
Holley provided bung
5.0 exhaust hanger in place
You can also see the Holley transmission wiring harness has been installed
Here is the harness as shipped
There are several loose wires included with the holley, reverse trigger, od on off, and others
You can also see the included harness for the optimal transmission line pressure transducer which I plan to add to our 4r70w
I thought it was interesting that all 10 pins are populated in the 4r70w connector, this is the 98-01 4r70w harness
Interesting, during setup we will be telling the new computer what trans we have so I assume this works with both 92-97 versions of the 4r as well as our 98-01
Style solenoids
Hard to wrap your head around when you are the guy always moving these pins around and deleting power feeds? How can the Holley computer move battery power from one wire to a different one and replace it with the solenoid trigger wire?? It maybe that the wiring changes for our 98-01 specific model happen upstream and they just leave all 10 pins in place.
Yes I have a tendency to over think things.
More on the “loose wires” in the 4r70w Holley harness
Compared to the wiring I normally have to do for a v6 to v8 conversion this is a breath of fresh air. Getting the 07 truck can bus system to be happy with it is another story since the 07 sohc pcm was part of the system. More on that later as we get deeper into this
This Holley system would be perfect for say a 1988 bronco ii that was going 5.0 lol lol 20 years later!!
The Holley harness includes connectors for both types of 4r70w oss sensors just fyi
Holley wiring harness is very high quality
