On most D-jetronic engines, the fuel injector wiring plugs are hard and brittle, and the boots are torn or missing altogether. You may say, "If it is working, why fix it? Watch the videos below to understand why this is important and how easy it would be for you to do it yourself.
Product Details
This kit contains:
- Eight new original-style wiring plugs with new wire tails ( if needed)
- Special tool to remove individual wires from the white plug cover
- 20 but connectors - small size
- Shrink wrap tubing to cover splices
- 8 custom silicone caps
- Full video instructions by Kent Bergsma
If you replace the complete set, you will need 16 crimp connectors (20 are included). If you cut the shrink tubing into 1 1/4 to 1 1/2 (max) pieces, you will have enough to cover 16 connectors.
This is what the finished product will look like on an original Bosch fuel injector.
Due to age and heat, most of the wire plug covers are brittle, cracked, or broken.
