Help with Glowshift boost gauge install...

[ST_Bo]

I have a 2018 fiesta st I'm trying to install a glowshift boost gauge I just don't no where to connect everything for the constant power I had it fuse tapped into the horn for ignition source I had it fused tapped into the radio for ground I connected it to the ground in the headlight switch and headlight source I had it plugged into a purple an white wire of the headlight switch I think the ground or headlight source switch is where I'm having the problem I'm clueless with cars but I love my fiesta and I want to do everything my self with this car and learn along the way any help would be appreciated

Did you get this figured out? If not, I will crawl around under my dashboard and see if I can remember which wires I ran where, since the interior is currently stripped out of my car and this would be fairly easy.

No I still didn't get it figured out the only way I got it to work is running all 3 wires straight to the battery with a fuse I tried multiple fuses for the ignition wire and can not get it figured out

oh yeah do NOT do that. Okay. I'll crawl around in there when I can and see if I can figure out which wire went where.

I recently installed a GlowShift oil pressure/temperature gauge. I tapped into power in the glovebox area fuse box. I used fuse taps to hook the constant up into the brake light fuse (10amp) and used the wiper fuse (20amp) for the ignition source. Seems to work fine so far. Also, note that the left side is the "feed" side and the right is the load side, so with the piggyback style fuse taps, you'll want the wire leading off to the right. For the ground I hooked it up to an existing ground at the bottom of the drivers side kick panel, that's right below the OBD2 port and hood pop, down by the floor. I didn't bother hooking up the dimmer wire to a headlight source, full bright all the time is fine for me.
