TFI coil mounting

I am not going to keep the old round coil as a back up. Do I have to mount the TFI to the engine or can it be mounted to the fender. Do I just splice into the existing wires or is there a adapter to buy, connection Distributor to TFI? Should I keep the wires as short as possible?

Re: TFI coil mounting

Cindy You don't have to bolt the coil to the engine but make sure the coil bracket has a good ground and the coil wire is kept away from outher wireing so as to keep raido noise down and keep the dreaded cross fireing from happening. You can splice new ends to the existing coil wires and connect to the TFI or you can buy the plug for a TFI coil and splice ends onto the wires to fit into the old coil adapter on my jeep I just cut the old adapter off and sodered on new spade conectors and it works great. Hope this helps

Re: TFI coil mounting

It doesn't matter how long the low voltage lead wires to the coil are.
You want to keep the high voltage coil to distributor wire a reasonable length.

You can just add wire and a female spade connector, and attach right to the TFI coil...
I recommend using the proper TFI coil connector.

TFI Coil Connectors.
(NAPA) TFI Coil Connector, P/N ICC1, $13.
Standard Ignition Motorcraft TFI Coil Connector, P/N S-539 $11.

Re: TFI coil mounting

Hey Cindy. To mount the coil, I took a flat piece of steel and drilled two holes to match the stock holes on the engine. I then mounted the coil to this. I painted it black, bolted it to the engine with the two stock bolts, and presto! I know this is not as intricate as some of the guys on here do but, it was easy and I could do it myself. Chad

Re: TFI coil mounting

Mid 80's Fords have some interesting brackets. I got mine from a Crown Vic. It was bolted to inner fender well(no engine vibration). Some also have pretty long coil wires. I also found the connector and a rubber connector cover I think from a Taurus or Escort.

Re: TFI coil mounting

I took a piece of galvanized angle that already had a bunch of holes cut in it and mounted the coil to it, then drilled into the passenger side fender using some of the pre-drilled holes in the angle. I mounted everything almost under the battery traywith the idea that it would be protected somewhat from water blown by the fan. I was at the Danial Boone Jeep Jamboree last week and it did not short out even tho I had muddy water everywhere under the hood, including the top of the air cleaner. By the way, I was just using spade tip connectors on the coil.

I did leave the old coil and lead on the block. If I do loose the TFI, I can change back quickly.
