I have emailed racetronixs twice and tried to contact them on ls1tech now with no response. I like their harnesses but don't know exactly what I need for my new setup?

I am doing dual 400 walbros and I want to put the second pump on a Hobbs switch. Do I just buy two of the same harnesses and put the Hobbs switch in line of the ground or is there more wiring involved with the Hobbs switch? If so what harness works with the 03 silverado's?

If I have to I will contact a racetronix dealer, I just figured it would be cheaper gettin it directly off their website.

Any input would be great! I hate wiring and their harness really cleans things up.

 

I forgot to mention that I have an 05 fuel tank and bucket that the 400's will go into.

 

I'm going to bump this up. I need to figure out my second harness

I have contacted racetronix with two more emails and tried to pm them on ls1tech with no results. I even called tsp and lingerfelter and they couldn't help me with the second pump harness. They couldn't even tell me what the dual intermediate harness looks like.

I did get the main pump hot wire harness. I just need to know which harness to run the second pump?

Anyone?

 

I guess I'll try to build one.

 

Did you check your spam folder? They have always been good about returning emails. I'm surprised to hear this.

 

I go through my junk folder daily. So that's not the case. I will try emailing them one more time. But I've pretty much given up hope on them.

I'm pretty sure I know which harness I need but no one can tell me what the harness consists of and their site doesn't show either.

 

I can second the lack of communication by Racetronix, I emailed them Thursday and still no response. Pretty bad if you ask me, but with enough reading here I was able to figure out which harness I needed and just ordered it.

 

Yes. I have read through so many builds with dual pumps trying to find the second pump harness I need. I remember reading someone's thread where they modified a specific harness and I can't find it again.

I'll figure it out. If I have to I will just buy a second main harness and use it with the Hobbs switch. I think that I need racetronix intermediate dual harness, but I'm not sure.
