Renix 4.0L wiring help

[eaglescout526]

First, Ωhm ive dug through the electrical manual and for the life of me I cannot find this one wire on C104 at cavity F, blue wire. Have no idea where it leads I suspect C103 or C105

 

Anyone with an 86 4.0L, can I get some help on seeing where this one wire goes? I have my doubts I need it but I dont want to remove it if I find out I will need it later on. C104 is a ten wire connector that looks different from the rest at the passenger side by the shock tower or relay center. 

 

I will follow up if I need to figure out where any others go.

In the 87 electric manual, page 20, lower left of the ECU, Sync Ground.

 

From C104, to C105, to C231.

 

 

(Double check the wiring.  I have found the manual to less than 100% accurate.)

Your right about accuracy. 88Elect Manual calls circuit SYNC Supply 7.1V. I do believe 88 corrected mistakes made in the 87 manual. Still both 87&88 show C104_F to C201_C16 as being part of the Engine Harness (E) while actually its part of the Engine Control Harness (EC).

Ok good I can delete this wire.

 

Thank you so much! I must’ve glossed over that when searching.
