Product Details

The MSD 7786 CAN-Bus Extension Harness is a 6-foot extension cable designed to expand wiring reach within the MSD Power Grid ignition system. When modules cannot be mounted close to the CAN-Bus hub, this harness provides the additional length needed to bridge the gap without cutting or splicing existing wiring.

All MSD Power Grid modules communicate through the CAN-Bus network, and proper harness length is essential for clean, flexible installations. This extension allows you to position Power Grid modules — such as boost retard, launch control, or data logging units — wherever they best fit in the vehicle without compromising signal integrity.

Key Features:

  • 6-foot (72-inch) length for flexible module placement
  • 6-pin connector matches the native CAN-Bus harness standard
  • Plug-and-play design — no cutting or splicing required
  • Compatible with the MSD Power Grid 4-Connector CAN-Bus Hub (PN 7740)
  • Works with all Power Grid CAN-Bus accessory modules
  • Also available in 4-foot length (PN 7784) for shorter routing needs
  • Legal for use on emissions-controlled, non-emissions-controlled, and racing-only vehicles

The MSD 7786 is sold individually and is an essential accessory for any Power Grid system build where modules are remotely mounted or routing space is limited.

Excellent product. Prompt delivery. Will continue use Autoplicity when needed.

Found the parts I needed for my vehicle's TPMS system that I could not get anywhere else. They were a better price than any of the other online stores and got my order shipped out in a timely fashion.

Excellent business. This is my second purchase and there will be more! I ordered my parts over the holiday weekend and they mailed them the Tuesday after Labor Day. The absolute BEST pricing you will get. You will not find a lower price else ware. The shipping doesn't even take forever like most places you get great pricing. Communication is excellent, the site is very easy to use and navigate. I will be doing business with Autoplicity.com many more times and highly recommend them.

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Best price I could find on the net and super fast shipping.

Very fast shipping, lowest prices on the web.

Fast shipping, good communication, a pleasure to do business with. I would definitely buy from again.
