The wiring plug covers must be removed with a special tool in order to install these boots. The old covers will break when you try to remove them. We recommend you buy new wiring covers when replacing either my aftermarket custom-made silicone boots or the original rubber boots.
You can use these to remove the wires and just replace the plug cover on your D-Jet V8 engine. Most of the originals are brittle or broken due to heat. As an alternative you can use butt connectors and wire them into your existing harness.
In Kent's 32-minute video on rewiring the plugs on your D-jetronic fuel injectors, he will walk you through the two options on how you can use this kit - then show you how in do it and finally give you some tips on automotive wire splicing using the best tools and supplies.

These plugs will NOT work on your original injectors. They will ONLY work on our new replacements (see below). These plugs are a good alternative to the damaged originals on your D-Jetronic fuel-injected engine only if you are installing our new injectors.
These are the critical seals that go on the D-jetronic fuel injectors. If they leak air, your engine with idle high, start poorly and run lean, which can damage the pistons. We recommend you replace these whenever you remove and replace the injectors.
WARNING: MAKE CERTAIN your current injectors are yellow at the top. A restocking fee will apply if you place an order in error. For the 3.5 engine ONLY. See related products below if you have a 4.5.
