Guys,

Need to do some wiring on the car and am looking for the right size heat shrink. Some people advertise it in mm, some as a fraction. So what size do we need for our cars as a fraction? I believe the wire is 18ga...

Thanks,
Jonny

 

How many cables are you using that will be 16ga.

 

You should get like 1/8 or so. Get different sizes just to make sure.

 

I would first buy a assorted size package. Once you've determined your ideal head shrink, buy a roll.
