Guys,

For those looking for it, there is a wiring diagram on our website showing you how to connect our Infinitybox wiring system to the GM LS engine harness and ECU. You can find this in the Resources section of our website.

This shows you how to connect the key-on power from the POWERCELL to the harness. It also shows you how to wire the cooling fan and fuel pump triggers from the ECU into the MASTERCELL. This will let the POWERCELLs control the fan and fuel pump locally without having to add extra relays.

There is a post on our blog that goes through this in more detail. Click on this link to get there. You can download a PDF of this wiring diagram from the blog post.

This diagram will work for the LS3, E-Rod and LS7 wiring harnesses.

Please let us know if you have questions.
