Product Details

The American Autowire 27670 is a Factory Fit engine wiring harness designed for V8 engines with manual transmissions and modified for use with High Energy Ignition (HEI) distributors. This professionally manufactured harness is built to original General Motors specifications, providing a plug-and-play restoration solution for classic GM vehicles.

Key Features:

  • Modified for 12-volt HEI ignition system with standard 12-volt feed (replaces original resistor wire)
  • Includes connector for GM large cap distributor
  • Fully assembled, taped, and ready to install upon arrival
  • Plugs into firewall in factory location with original routing in engine compartment
  • Contains wiring for ignition system, starter, heater blower, and temperature/oil pressure sender wires
  • Manufactured to original GM specifications for authentic restoration

This harness is designed to work in combination with a front light harness to accomplish most functions under the hood of early GM vehicles. The HEI modification eliminates the resistance wire found in original points-style ignition systems, providing proper voltage for modern electronic ignition systems. If not using a GM large cap HEI distributor, the connector end may need to be replaced to match your specific ignition system.

Great so far.

So far so good. If if ship tomorrow you get five stars. Said it was in stock. And you shipped on time. great job

Very detailed list of part fitment. Radiator fits and functions very well. BUT, and this may be no fault of Autoplicity, I received the radiator w/holes punched in the box and some of the cooling fins bent. It wasn't bad enough to warrant a return, thoug

Great experience overall!!

incredibly fast processing, inventory, and price.shipped next day. awesome site

The product came at the very last minute. So we had to do something different plus the "return" directions on the website were not clear, i.e. the return process is not easily executed.

Very friendly and fast shipping

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Need it quick as possible please need it for my license. Thanks y'all are the cheapest auto part store around.

Thank you ! Easy

Ordered a Thule hitch and was a little skeptical because I hadn't heard of this company. I was pleasantly surprised by the quickness of response when I ordered, I received an email immediately, and the order arrived just 2 days after it was ordered. This company goes to the top of my list.

Everything I have gotten from Autoplicity has arrived in perfect condition and quickly. The prices are great and the product selection very good. I always look to autoplicity when I'm looking for something new for the Jeep.

I was very happy with Autoplicity and my order of the MMRAD-MIA-90X Mishimoto radiator for my Miata. I am in the process of building a Spec-Miata for racing and trying to keep the costs down. I found Autoplicity to have the best prices on the net. I received the rad real quick. There was a problem with the radiator but the guys at Autoplicity were easy to work with and I am expecting the new radiator in a week or so.
