were does the ground for the back lights go?

 

Here's a thought for drilling the manifold. Let the engine completely cool, then just before drilling through start the engine and let it idle while you drill through. Supposedly it keeps the metal shavings out of the turbo. Banks does it in thier shop, so I think it might work. I haven't tried it because I suck at everything electrical and had a shop install my guages, but its an option.

 

You can ground your lights anywhere you want.

 

I'd be careful about drilling with the engine running. Someone with experience drilling and tapping is one thing, but a novice drilling is another.

If the bit or tap snaps... it will get ugly. I drilled on mine with a cold engine, if I broke the bit or tap; I still could remove the manifold to get rid of the pieces.

I drilled and tapped with cutting oil, vacuuming asI wentand fished out the fe filings with a pen magnet. I also put some hi-temp rated compound on the threads of the pyrometer sensor. (I gotthe compoundat Napa)

Take your time, drill slow, tap slowlyturning forward and backward. Apply the cutting oil. Avoid using a crescent wrench to tap with. Use a T-Handle instead, this puts torque and pressure equally on the tap. (Lessening the chance to snap the tap.)

As for the ground, I found a convenient sheet metal screw. Scratch the paint under the screw a little to make better electrical contact and put a little compound on the wire andmetal area.

Good luck! If I can do it anyone can.

 

Check the DIY section. I did a write up on how to do an Autometer gauge install up there complete with PLENTY of pics !!

 

Mayfair check post #5 [8D]. Fronedaddy already put up the link

 

Oh yeah, there it is

LOL !!!

 

YA had me affraid there mayfair, though your were getting senile just like sharx
