Carlos, if you're thinking of installing very many more electrical devices the FZ1 fuzeblock is the way to go IMO. Its slick. It allows 6 devices that can all be changed from switched to constant by simply moving the fuse over a space. A very handy design especially when you're not sure how you want to set things up, like maybe for a TPMS or GPS. Other reasons too. Installing it now is very little added effort and could save you lots of time in the future.
I didn't think I'd need the space for 6 new gadgets but I seemed to have filled it. GPS, heated grips, heated clothes, fork lights, mirror lights, TPMS.
I expect you know alll about the great resources in the Articles section, but just in case here's a start ...
Curt Gran's Farkle-Accessory-Wiring-Primer Definitely worth a read - or 2 (Thx again Curt for all your guidance and inspiration)
ARTICLE ST1300-Fuse-Block-Install-(FZ-1) One idea.
I had a quad harness on my ST. At the time choosing it over a fuse block seemed like the better option although I'm not sure why now that I`ve had both setups.
One more thing - If you do the fuseblock thing I'd suggest a visit to Princess Auto (Cdn version of Harbor Freight for our US friends). They have colour coded spools of automotive wiring in several gauges. I also picked up some large heat shrink tube (3/8" I think) to run my wiring in. Feed several wires thru each tube as added protection for the wires and a nice clean install, -- don't shrink the tube. Looks just like a factory install. ;-)
Oh ... and isn't raising the tank on an ST needed periodically anyway? The air filter is in there IIRC. That's the way to go IMO. Raising the tank is simple. Honda even gives a you prop rod. Still got yours?
Anyway ... if you need some hands-on help I'm sure one or more of us would be happy to be there for you. Just ask. We could even have an impromptu tech day somewhere. Several others will need things done too, I expect.
Cheers,
