Me toooooo!!!!!!!!!!! I have family friends forum all asking me.... no sweat! She will run, I want to hear the cam through the TMH mendrel, "catless dual" exhaust and spin techs!!!!!!!!!!!!!!
I haver done a bunch more wiring.......... so back to the pics
First up I needed to finish the under hood wiring
The alternator power feed for the IVR (internal voltage regulator) is the yellow and white wire on v8 trucks this is headed to the power dist box and a 30 amp mini fuse. 2002+ trucks like our ranger here, this wire has fusible links internal and goes directly to the PJB battery + post.
I do not like the inline fusible links, so when I do these trucks I add a fuse to the stock fuse box (SJB smart junction box 05+ ranger)
The green/red wire is the feed from instrument cluster battery light to the IVR. These two wires are found in the 12 pin C139 connector on the truck side.
I ran two new wires from the ALT IVR to the truck and built a male side C139, now our engine functions will plug into the truck like factory.
Alternator wiring cannot just be connected to the SJB
To add a fuse to the stock SJB I robbed a few wires and pigtails/fuses from another 05 Ranger harness I have (donor)
Before:
I added a 30 amp fuse for out alternator IVR feed AND I added 3 more..........wooooooohahhahaha
Now I have 3 fused feeds of battery + I can utilize simply by adding the fuse
The alternator IVR power wire does not just run directly to the SJB, in order to make it like factory and easier to remove the engine this wire is run through connector C139....more on that in a minute
red wire near brake booster is coming from new fuse, to truck side of C139 (female)
I created a new male C139 so our wiring will plug into the truck just like stock
The 5.0 harness uses a similar 12 pin plug, but it is also female....
Other wires that run through here are oil pressure switch to instrument cluster
dark green/white, careful here the dark green with white on the 5.0 side actually goes to the oil level / temp switch on the side of the pan. I ran a new wire directly from this plug to the stock oil pressure switch
AC high pressure switch is Red/Yellow and black/white, all of these wires pass through the the new male C139
white with pink and a black ground are also for the oil level switch, this truck is not equipped with.
While I am in here in the SJB, it is time to bypass the PATS control over the starter relay
This truck will have no PATS (Holley PCM) 07 Ranger PATS is part of the PCM and that went away
the starter relay ground control from PCM is right here, DB/OR
I will use a factory pigtail to create a new ground right near SJB
now the ignition switch has control over the starter relay
Alternator wiring was removed from engine, re-wrapped and then laid back in place.
One more thing to do to finish our 5.0 conversion wiring here at the SJB
5.0 battery harness leads for alternator charging wire and battery + terminals are the wrong shape to fit our 05 Ranger SJB
marked and carefully cut with a grinder, then file
Engine and truck were covered for the grinding event. These are soft metal? easy to cut
Also had to snip a little plastic
fits like factory
SJB is done...for now I may need to add some mini fuses as well as I install all of these electronics!!
