The length completely depends on what areas you want to connect to. I remember making a 20" and a 24" but I don't remember the third or where I connected which (it was over a year ago).

 

Can you check your pm..............

 

WOW!! That cheap huh...good to know this..someone is making a killing selling these I think.hmmm

 

bump.......................

 

Anybody know the lengths on these yet?
And I just need to add an additional ground from the stock battery, can I just do step 1 in Black Betty's install and be done?

 

All you need to do is ground the inner fenders to the block and to the negative terminal.

The throttle body grounding is BS, waste of time and money...lol

 

Anyone know what lengths needed?

 

Yeah, but what is YOUR time worth. Sometimes its better to get someone good at a reasonable price (Cough Black Betty Cough), than attempt making them and loosing your time and money.

 

Grab some string and start measuring the engine bay.

 

or.. get some 4gauge amp kit wire and use that to measure freely & cut to within length needed.

then use some protective wire cover

 

That's what I did, but didn't know if he wanted to know length prior to buying a set amount of wire.

 

I took the hassle out of measuring. I made a DIY thread to make your own grounding kit. It includes wire lengths, connections, mounting points, and installation photos and instructions. No hassle, no guessing, no measuring, less time!! Check the thread out here:

Thanks for this

 

To the OP, the TechFlex gives those wires a great look. I also made my own grounding wires, except I used the protective ribbed plastic tubbing thats prominent in the engine bay of our cars.

 

Great writeup. Still holding up pretty good!
