Many of you have already or are considering hardwiring. I appreciate a clean "stealthy" installation for all electronics in my vehicle. If it looks like it doesn't belong, it doesn't. Anyway, in my hardwiring forays I've learned a few tricks that I wanted to share with those of you who may or may not have heard these yet.
1. Mounting several items in close proximity provides good camoflage for LEOs looking in your windshield.
2. If possible, run a 12V and ground wire up into the roof from your fuse box. This way you can hardwire several items without having to extend each of their wires down the a-frame. Integrate an on/off switch with this wire or your main power hub should you add one.
3. Break off the "clip" on the phone-type plug that goes into your V1. I've not had a problem with the plug wiggling loose or my V1 detaching from the windshield and needing to be "caught" by the plug. Breaking off the clip allows you to remove the V1 from view of a LEO completely in one fluid motion without having to mess around with the stupid plug clips if by God's will you get pulled over. (For added stealthy-ness, use an aftermarket spring-loaded retractable phone line)
4. Invest in a remote display ASAP and hide the V1 behind your RVM.
5. Use electrical tape or shrink-tubing on EVERYTHING after using butt connectors, twist-ons, or M/F ends. Have a qualified buddy check your rigging.
6. Offer your services to anyone and everyone.
I like to post every bit of knowledge I have when I first get to a forum. I'm sorry if this topic has been covered already but review never hurts.
In line with #6, I am frequently all over Indiana (mostly Northern) and am more than willing to help anyone do a clean and safe hardwire in any vehicle at no charges.
I hope a good number of you have more to add to this....
