I am trying to wire up my Painless Harness. I've got the dash pretty much done. Time to route the wires thru the firewall and I've come across a perplexing problem.
I have chosen to use the Holley Sniper TBI system, including their HyperSpark distributor with Coil and Capacitative Box. Should be Plug N Play, right?
The HyperSpark coil has no "-" nor "+" nuts on it, it is TFI style plug n play. The directions from Holley specifically say in regards to the coil's connections, "this is the only wire that makes electrical contact with the coil + ( or -) terminal", in reference to the Orange or Brn/Orange wires that come from CD box. So no other connections.
Which leads me to my yellow lines sheet. I have the Engine module from the middle of the dash (painless harness), and broke down the 15 wires. Reverse switch and Neutral safety I can figure out once I get the switch mounted on the C4. There's 6 wires that I am unsure what to do with. There are 2 separate Blu #900 wires that say switched 12V source, one labeled in Ign module. I'm thinking that one goes to the switched 12V for Sniper. Right?
But what's the 2nd Blu one for?
There are 2 separate wires labeled #999 Grey/Yellow, both labeled origin coil (-), one is again part of the ign module. Where do they go?
Then there's #920 Red/Grn Coil (+), comes from main fuse block and functions as a switched 12V +. I have no clue what to do with this wire.
Painless gives some great diagrams, but they all have coils with lugs to connect the wires to, and there's no lugs on thos coil. So, delete all coil wires?
Lastly, #954 Wht/Blk is for electric choke, but I see no connections for it on the Sniper wiring diagram. So delete as well?
I know, you're thinking those additional leads on the 10 pin connector from the TBI could help, right? Well, imput #1 is gen triggered A/C relay, #2 is a programmable grnd input, #3 and #4 are for fan relays, #5 is a gnd triggered A/C relay, I'm using the dark brown to connect to my tachometer #923 Grn. That's it for wires.
So, what do I do with all those harness wires?
Just delete coil wires? I'm definitely not seeing this clearly. At least I have one wire for each side of the starter solenoid identified.
In the mean time, I'll start researching my Explorer Serpentine Alternator wiring set up.
Ha!
Any help is very much appreciated.
Thx
