Lets face it! Like it or not, electronics have taken over the automotive world. Whether you’re working on the grocery getter or swapping your classic cruiser over to EFI. Sooner or later you’re going to have to repair or replace a connector and possibly purchase a crimping tool.


Here at Holley and MSD we understand your dilemma. That’s why we’ve put together a great selection of specialty connectors for use with Holley and MSD Electronics, as well as a complete selection for popular aftermarket and OEM style connectors. And don’t forget about our full line of crimping tools to help make that next wiring job a little less frustrating!

Whether you’re wiring a Dominator ecu with our complete J2 / J4 connector and pin kit p#558-408, or you just need to replace an individual sensor connector such as the TPS, Map, or even a wide band O2 we’ve got you covered. We carry replacement connectors and pins for most any sensor found on a Holley or MSD wiring harness. You’ll also find engine specific OEM connectors, like Molex, Delphi and Metri-pack for late model engines.


If you need a secure, corrosion and vibration resistant connection, we can help you with that too! We have connector and pin kits in popular Weathertight, Weatherpack, and Duetsch, designs. These electrical connectors were designed for higher electrical draw and current demand compared to conventional crimped terminals.


Get a crimp! That pair of plain old pliars just isn’t going to cut it when it comes to crimping today’s connector pins. Special connectors require special tools. Once again Holley and MSD have you covered. If your crimping Holley EFI connectors then you better grab one of Holley’s crimp tools, part # 567-100.
