I'm planning to do my wires when I do my headers over Christmas. I also know the guy that started the thread hasn't done his yet either. So, this is some good & timely info. Are there instructions on MSD's website? I've never made plug wires. I'm not stupid and could probably figure it out, but it's always nice to have some idea what you're doing. What did you use for your practice crimps? What looms did you use? The Made For You looms? Did you use MSD wire, boots and crimper?

I was planning to maybe use the MSD heat shielding. Is the Moroso better? Where did you get it, and all the other stuff for that matter?

Thanks.

 

I had planned on taking old things made of plastic that I had lying around, cutting and drilling them to make looms.

The made for you kits are nice, but way too much money for a few pieces of plastic.

 

When I did the OTVC thing, the only wires I ran over the covers were #6 and #8. They were the only wires that had header clearance problems (burnt boots and such). #5 was close but a tie wrap took care of that one. The rest I ran under the headers since there was plenty of room .

When you install the firesleeves, turn them inside out, soak them in WD40, slip the plug boot through the ring in the end and then push the plug boot back through outside in (no tools - just fingers). WD is the key to getting these guys on easy .

EDIT: I also used this stuff with some tie wraps around the wires, pn 2592K61 from McMasterCarr http://www.mcmaster.com/. Nothing has burned through yet. If you do use the McMaster stuff, wear gloves since it has fiberglass in it.

 

HERE IS YOUR SHOPPING LIST:

Summit part numbers:

WIRE SET: MOR-73225

BOOTS BECAUSE SET COMES WITH ANGLED BOOTS AND YOU NEED STRAIGHT ONES TO GO ON THE OPTI: MOR-72060

WIRE SLEEVE. THE MOST IMPORTANT PART ABOUT THIS AWESOME INSTALL: MOR-72011

WIRE LOOMS: MFY-5035612

(all these pieces match so nice I wish this was my set!!!) I have red looms, red wires, red sleeving with some standout bluish moroso shrink tubing holding on the silicone sleeving.

The guys already showed you what crimp tool to buy:

This wire set would look AWESOME! Especially if you had hi-miller hoses too!!! ...


Buy a can of spray silicone lubricant and DONT use wd-40 it is messy and oil isn't good on the silicone rubber. use silicone spray on the silicone rubber. It will come out very clean, very professional and very nice. Use a small handheld torch to heat the shrink tubing holding it far enough away so you dont dry and scorch the surface. let the heat rise under it to shrink. It is FUN! Reminds me of shrinkidinks when I was a little kid

You might want to order a large universal kit of shrink tube. This stuff has come in handy while fixing my camaro. There are very few parts of my wire harness that have not been retouched and sealed off from the elements. I didn't have enough little moroso shrink tube pieces for my wire set because I bought them from someone on here a while backa nd they lost a few and I used the larger size (but not the largest) shrink tube and it worked Perfect. A large universal set of zip ties is awesome for the garage too. I use those things like there is no tomorrow and when making wire harnesses they are absolutely necessary. my car would be shaking apart without them.

I Made my opti harness to pretty much match my wires. Check it out!

 

I'm getting ready to order the stuff for my wires and I was curious if anyone had ever used the 10.4 mm Made For You looms, as opposed to the 8mm, with 8.5 mm wire? I can't really think of any reason not to use them. Is there a good reason someone wouldn't want to use the larger diameter looms? I may also be using some heat wrap, but I'm not sure about wrapping the entire wire, or just where it would be close to the header.

 

Use some brake fluid on the wires to put the wire through the boot and then put the end on and pull it back. It will slide like greased snot and won.t dry up on ya, Wipe off excess fluid. It will NOT hurt the wires.

Done it this way for 30+ years and haven't hurt a wire yet.

 

Thanks for the info.

I have another question. How important is heat shielding for both the wires & boots? The reason I ask is because it's pretty expensive. Will it extend the life of the wire even in areas where they may not be in close proximity to the headers? The MSD heat shielding is only available in 25 foot rolls. Or at least that's the smallest quantity they seem to sell. The price tag of making your own wires seems to add up pretty quick.

 

Look again you can get it in 3 foot or 6" lengths I believe.
It is very important but ya don't have to do the whole wire just around the headers.
