- 1976 CJ7 Jeep with a engine/tranny/wiring harness out of a 1988 s10 blazer 4.3l v6 with th700r4 automatic tranny and a cj7 Dana 300 transfer case with Novak adapter.
Complete wiring harness from the s10 blazer. Painted with HOT PINK Pearl paint with standard sized metallic halographic pink flakes. Painted by me -a newb. New rear, front and side three wire LED lights, New parts, new custom dash-by me And a lot of guidance from fellow jeepers and lots of prayers etc.... :p
I used to have my GM TBI harness (ECM main power) connected DIRECTLY to my Ignition Coil.... But since want to install a RELAY...
Please let me know if this is the correct way to wire it... If you have a better wiring idea PLEASE share your thoughts...
(I am using a 5 pin relay as I don't have any 4 pins)
85 - Ground
86 - Connected to Ignition Coil + power (Is this OKAY?)
87 - Connected to ECM power IN
87a - Not Used
30 - Fused (5amp)-- Should it be a different amp? Directly to +/power on battery
HOPE TO HEAR FROM YOU ELECTRICAL SMARTY PANTS!
