Plug Leads

After putting the general engine assembly back together, it was time to plumb some ignition leads to the new coil locations.
I bought an MSD universal engine ignition lead kit which has the plug ends already crimped, but long lengths of lead to be custom cut to length by the installer,
After i routed the leads and marked them up for length, i was surprised to find the kit didn't contain the type of coil connector used by the LS individual coils, i had assumed these would be something common, but not to be.

Plenty of different connectors and caps, including some spares....except the the LS coil type connectors i needed.









The top 2 connectors come in the kit, i found some connectors on the web after feeling like i was being mugged by the local ignition specialists.

The black 90 deg boot came in an LS connector kit from Taylors in the U.S.





After routing the leads, mark up the length of lead to the center of the right angle boot.
I used some zip ties to hold them in place while i adjusted angles and lengths.









I used the crimp length guide and crimp tool included in the MSD ignition kit.
Insert the lead into the tool lining up the mark you made to the left side of the holder, then cut through the silicon lead cover while rotating the lead.
The holder prevents the knife from cutting too deep.




After cutting the silicon sheath and pulling off, fold the lead conductor back under the lead and push into the crimp connector, then insert into the crimp tool, and squeeze together in a vice.








I used the grey 90 deg boots supplied in the MSD kit for a lower profile look over the larger Taylors boots.









The MSD kit also comes with cylinder lead number tags.










Finished.
