I'm getting ready to install a Dakota Digital CHT. Here are my questions:
1. What is the shrink wrap for on the copper wire? Mine came with it as shown in the photo. Do I shrink it once installed? It seems too big to shrink down over the wire.  2. I'm installing this on #3 cylinder. Looks like I'll have to bend the spark plug connector. Has anyone done this, or must I grind out a space for it? 3. What circuit should I install this on at the fuse box? The red wire goes to "fused +12V with key on". 4. Is the blue night dimming input required? If so, where does it go on the fuse box? 5. Any tips for running the wire in the engine bay? I was planning on running the wire from the firewall on the driver's side, to the trunk wall, then along that to the #3 cylinder location. The other way would be along the fire wall, but then wires have to cross over the engine and a bunch of other spaghetti to get to #3. Thanks! -Jeff ---------- Attached thumbnail(s)

Very accurate gauge. Do they still come with that 12ft lead of did they get around to shortening it a bit?

Nope - options are still "a lot of extra", or "too short" but I just gathered all the excess and zip-tied it into a bundle. It sits on the bottom of the console behind the gauge panel. |

EGT and CHT leads can be very easily shortened; after all, they're just wires. The trick is realizing that you need to thread the wires out of the braided lead (or trim it) and then heat-shrink the end of the braiding to avoid fraying. https://thesensorconnection.com/videos/how-...be-sensor-cable |

Notice that there's not a different gauge supplied whether you choose the long or short harness...? Trim away. GA |
