1995 F150 Custom Wiring
Hey dudes, been busy with the site so I decided to take a break and post this up really quick. Basically, It's an MSD coil and an MSD ignition control box that I installed. The MSD coil can replace the OEM coil without any issue. You just unplug the spark plug cable, then unplug the harness from the old coil, unscrew it and then pull it out of the bracket. Clean off the bracket, repaint it, or leave it be, it's up to you. After you figure out what you want to do, just drop in the new MSD coil (or any other coil), screw it down, (do not over tighten), plug the OEM wire harness into your new coil and don't forget the put the spark plug cable back on. Piece of cake!

Here is where it gets tricky, I had to tie in an MSD ignition control box into the same system! I also made my own harness and used weather pack connectors. The weather pack connectors are weather proof and look factory. I think they are a must for anyone doing any kind of wiring under the hood.

The parts used are as follows:

MSD Ignition 6200 - MSD 6A CD Ignitions

MSD Ignition 8823 - MSD Vibration Mounts

MSD Ignition 8227 - MSD Blaster TFI Coils

MSD Ignition 8874 - MSD Universal Wiring Harnesses

Painless Wiring 70404 - Painless Performance Weatherpack Connectors - x2

Weatherpack crimpers, wire strippers, flexible tubing, electrical tape, wire ties, drill bits and a drill, some sockets and a ratchet. Pretty easy job, took about an hour.

OK the tools:

The most important tool is T-12 Weather Pack Terminal and Seal Crimper. It crimps Weather Pack terminal and seals in one cycle, it is the most expensive of the weatherpack crimpers BUT it does the job in one shot.

Quick specs: Features two double cavities, an orientation block and a ratchet mechanism to ensure that each crimp cycle is completed. Factory calibrated to be used only with Weather Pack terminals and seals. Wire range 20-14 gauge.

You will also need the T-3 Weather Pack Terminal Release Tool, designed solely to depress Weather Pack terminal retention barbs to allow terminal removal from tower or shroud, just in case you need to take it apart:

A set of wire cutters, wire strppers, some electrical tape (use the good stuff), tubing to protect the wires if you want and that's it for the tools.

Ok here are some pics of the parts that came with my weather pack kit, all kits are different, pay attention to what you order and for what size wire:

And special for this job, I am going to need to make a harness to tie the MSD components into the factory system - 1995 F150, the goal is not to cut into the factory wires just incase the MSD system has to come out :

OK lets begin, I will start with the harness, you want to remove about 1/4" MAX of the sleeving to expose the copper. I found it easier to slide the rubber seals over the wire before it is stripped so you may want to just do the same.

This is what you should have (the rubber sleeve should be over the wires shielding and not on the copper):

From here we place the terminals into the special weather pack crimper like so:

Below are the terminals that come with the kit, it is very important that you pay attention and make sure that you put the same style terminals into the connector end you are working on. Example, I used a 4 wire connector, on one connector the terminals are all male, and on the opposite connector it has all female terminals.



Note about the images above:

Notice the very top of the terminal has an open U shape to it, the extended part of the rubber seal MUST rest in there, the crimper crimps that metal U shape around the rubber very tightly to create the weather seal.

When placing the terminal into the crimper, it is very important to make sure it is completely flush with the crimper. Again, make sure the metal opening is hugging the rubber seal and then squeeze the crimper until it releases itself:

Here is what you should end up with:

From here, once you complete all your wires, you just slide them into their shrouds (connectors), push them in until you hear a click. Thats as simple as it is.

The shrouds - connectors - plastic ends:



Before I pushed the terminal into the connector, I wrapped all the wires in electrical tape, to keep it all together, neat and extra shielding. I then wrapped the taped wire in plastic high temp convoluted tubing:

Here is the complete harness that ties the MSD ignition control box into the coil on one end and the OEM system on the other:

Next I drilled out my fender well and mounted some rubber feet for the MSD box:

Here is the MSD box getting prepped for the weather pack connectors, I cut down the lines and then did the above steps to install the weather pack connector:

Next I replace the coil with the MSD coil and tie in my new harness:

Thats about it, now I have to redo all my wires with weather pack connectors!

Any questions, please ask away!

I forgot to mention that I used 14 gauge wire for this.

man that looks like it took a while, but the results look great!

That turned out awesome! I might have to try that since I already have most of the parts from my fox. The only difference is I have the 6AL, will that work? The only real difference I can find is the built in rev limiter.

Still will work with no problem dude. Any questions, just ask.

Ask and you shall receive... Do you have part numbers for the tools, and where did you get them? Those are tools I could definitely see getting a lot of use from! Those connectors may seem expensive at first, but I'm sure they pale in comparison to replacing a $2-300 ignition box, or any other equipment due to corrosion.

A few options here:

Tools and Parts Links (summitracing - cheapest):

Tools and Parts Links (terminalsupplyco):

Tools and Parts Links (amazon):

Basically, the crimper is the most important thing. The crimper I used does the crimp job in one phase, meaning one shot. The cheaper crimpers require two stages, so you crimp one way, repostion and finalize the job... kind of annoying.

If you plan on doing a good deal of wires over with these connectors, I would suggest getting the more costly crimper from Delphi Packard. The rest of the items, I would buy at summitracing in individual packs - buy the summit brand versions, it will be the cheapest and it will be the same design and quality as the expensive ones.

For the above job, I bought three of these:

Each kit comes with everything you will need. There are no extra parts so I would suggest for your first time around, also buy this:

Just make sure you buy for the correct gauge wire... VERY IMPORTANT! I hope this helps dude.

If your ignition control box is MSD, you can send it to them for repairs. I sent them two boxes, a 6 series and a 7 series recently for repairs. The bill, shipping both ways included was like 130.00 and now both boxes work.

Wow, I can honestly say that I have NEVER been on a site as informative, and helpful as this FTC. I :heartz: FTC! I'm gonna need to order some stickers for sure.
