First time installing nitrous......NEED HELP!
Now I have a few questions because electrical isnt my best department.
#1- Where is the best place to run a 12v switched source? Have to find one for the microedge and toggle switch but not sure where.
#2- On the microedge I have to splice into the TPS/WOT switch, is that the dark blue wire coming from the TPS sensor? And would I just splice into that?
#3- Where is the place place to find the tach signal? PCM? Crank Posistion sensor? Fuel Injector?
And also if anyone has the HSW solenoids, it shows blue/red wires in the intstructions coming off the solenoids, but they are ALL dark grey wires? which is which?
Sorry about all the questions guys, just wanna make sure Im doing everything correctly. Any input would be appreciated and also if you have any PICS that would be a PLUS!! thanks
). I need to install the bottle heater, switch plate panel, purge, FPSS, and microedge, & a timing tuner along with all else. HSW has a tech help line (service ticket) via e mail which is very helpful. You can also open up install diagrams & instuctions on the help page. I have been reading & studying the install process and would like to get it right in my headGood Luck
No but kinda wish I did. Probably would make it easier just to turn the ignition on and find what wire is a good 12v source.

Its just the green wire off the microedge is a 12v switched and I might splice that into the orange wire of the cigarette lighter. Also the purge will splice into it as well

The fuel injectors use a switched on 12V source... (pink wires)
I got the tach signal off the white wire coming from the PCM (pin 24 or something)
Also bought a test light and found a pink wire coming off the main harness and spliced into that
Everything looks good so far (I hope!) Got the microedge to power up and just gotta program the interface/microedge. Also finish up the triggering wires for the switch panel and should be on my way!!!
JL is right, pink is your switched source, for most of the accessories...if you're not using it for a high amp draw the factory harness will probably be okay. If you will be pulling a high amp draw, use a fuse tap that plugs into your factory fuse panel. I think Buss makes one that's available at most auto parts stores. If you still have any questions don't hesitate to ask.
