| Box to house coils |
| Four coils per box |
| Raised front of car and removed front wheels for ease of access. Re-purposed 3 foot fluorescent work light adds plenty of light. |
| Area selected to mount coil boxes, inside rear of fenders. One on drivers side and one on passenger side. |
| Supporting coil box in place to fabricate and fit mounting brackets. |
| Diagonal bend of a bracket. |
| Fitting brackets before welding |
| Brackets welded to boxes. |
| Bolted in place using existing running board and fender mount fastener locations |
| Holes drilled for spark plug wires (two wires per hole) |
| Plastic tubing will guard wires from chafing |
| Removing coil/injector wiring harness |
| Engine with harness and coils removed. There was also a harness for spark plug wires crossing over the engine I removed. |
| Coil/injector harness laid out on the table. |
| Each connector was labeled to identify corresponding cylinder |
| Dissecting the harness to extend the coil wires |
| Notching coil boxes for coil wire passage |
| Building spark plug wires |
| Lubricating spark plug boots in dish soap and water to ease assembly |
| 3/8 steel tubing used to slip spark plug wire through the boot |
| Stripping the spark plug wire one inch to add connector end |
| Crimping end on wire |
| Wood dowel with shrink tubing to serve as a depth gauge to set wire in boot. Boot depth is critical on HEMI engines for moisture seal purposes. |
| Black end of dowel inserted in wire connector, then wire is pulled through the boot until end of boot aligns with beginning of white shrink tubing |
| Routing spark plug wires to the coil boxes |
| Store bought wire separators, home made stand-offs |
| Installing coil ends on spark plug wires. Two styles were needed for each coil, one late model GM snap on type and one early push in. |
| I used the same 3/8 steel tube technique to slip the spark plug wire through the coil boot as I did with the Spark plug boot but with a shorter piece of tube |
| When the spark plug boots and connectors were all installed I connected the coil wires and the wiring was done |
| I labeled the box covers and made rubber gaskets for them |
