Hey guys,

I am looking at a the Painless Wiring CirKit Boss Circuit Fuse Block Kits. I plan on adding quite a few accessories to my truck (lights, amps, CB, etc). Here is a link:

Would using this get rid of the need to put a relay for every light, or would it simply get rid of the need to run a wire with an inline fuse to the battery every time you added an accessory?

I have the 70103 aux fuse kit. depending on your load it may or may not eliminate the need for relays, but it does eliminate the need for extra wires to the battery. Keep in mind the total load will need to be less than about 30 Amps, I think that is what the relay and the main power wire is capable of handling. In any case it makes for a very clean installation of accessories.

Would you recommend getting it? They have a version that has two 40 amp relays...would there be any disadvantage to getting that one?

How does it work? Is it simply a block of fuses or does it also provide a lead to switch on/off each particular fuse? I'm not really clear as to what all it does.

I ran one fat wire to the battery and stuck relays off that for most of my crap in the back(reverse lights, strobe, whirly lights, N2O bottle heater ect) The painless is a slick and easier but you could accomplish the same thing for cheaper. I will say my set up looks pretty scarry, bundles of wires and relays all over the place in my tool box:eek:

They are pricy but well made. Some have +12V all the time or a combo of +12 Hot and +12 V that is switched. The battery goes to the hot lead, the relay is connected to switched power and the hot lead to give switched power. In my case there is 1 +12 HOT and 3 +12 switched if I remember correctly. If you are running stuff that draws lots of amps (big lights etc) Then I'd go with the one with two 40A relays. In my case I have my radar detector, rain sensing wipers, and a few other low amp draw accy connecte up so the 30A unit is fine.

So you are saying that by using the relays built into the box you don't have to have external relays?

Anyone else?

I did a pro street vett (1971) and used one of the kits by painless, very easy to install and had everything that I needed then some extra for the pumps and such, if you are on the bridge of install and looks then go for it very easy and well marked kit(atleast the one I did).
