Hey Dev,I also used one of their harnesses, I gave up on getting any meaningful help from them and figured it out on my own... if you have any questions feel free to ask. One thing to always double check is some of the accessories, some like the electric fan circuit are fairly small wires, I only used them to wire the control side of the circuit then added relays tied directly to the battery to actually power the fans. I was very happy with mine but as you said about the instructions..... gotta figure it out on your own.
Thanks for the offer, I totally appreciate it.
By chance, I picked up a Painless instruction manual (at SEMA) a couple years back, WAY before I bought my AAW harness, so I could try and figure out what I'd need for re-wiring, and a couple things jump out:
- AAW includes a 6 page instruction "manual" whereas Painless includes a 100+ page book. The AAW harness is a nice quality piece but 6 pages of instructions versus 100? AAW's instructions are absolutely minimalist (at best), so if you're choosing between the two kits this may be a deciding factor for you.
- I haven't compared many of the wires between the AAW and Painless harnesses but those I've noticed are the same colors. Are both companies using the standard GM color coding for their harnesses? If so, then try and get your hands on a Painless instruction manual if you're using an AAW harness. Anyone who'd like me to check more wire colors should let me know and I'll be happy to do so.
I, like you, am using relays for all the items that need any type of significant power (fan, fuel pump, etc.) and using the AAW leads as the trigger only. Regardless of which wiring kit you use I have learned this is always a good practice. I'll be running 10 gauge leads from the power "out" side of my relays to the various accessories so resistance and heat should never be an issue.
One interesting thing I've never had to deal with before is a "ground trigger"; I've only ever used a positive triggers. While studying the various accessories I found the ground lead from the electric fan relay is connected to the engine mounted temp sensor, so when the sensor cycles between its 170 and 180 degree "on/off" temps it grounds the circuit and turns the fan on/off. Glad I'm taking my time and working through this stuff one item at a time!
LOTS to do in the next few days:
- Install the front bars of the roll cage; cannot place various electrical components until I know where the cage bars will be
- Front and rear master cylinders are on their way so I'm going to start running the hard lines along the chassis and to the calipers; I need these in place so I can figure out exactly where I want to place the brake pressure switch
- Once those things are taken care of I can continue pushing forward with the electrical
