    Excuse my ignorance, but how do I 'tap' into the ashtray light wire?

    Do I simply cut it, and splice in the power wire for the gauges?

    Any other methods or special connectors I should use?

    I used one of these, No need for cutting or splicing. You can get them anywhere they sell crimp on barrel type solderless connectors. Auto stores, maybe even Home depot, or Sears.

    This is another type,

    I will be adding electronic gauges soon. I'm going to tee off the oil sensor port to keep the stock gauge working.

    My question is about the temp sensor. Do I just remove all the thermovaccum stuff that's in the LH manifold port, and everything it connects to?

    And no my motor is no where near this filthy and unorganized anymore, this is how I bought it! lol

    Yes, all you need is a single vacuum line from the carburetor to the vacuum advance. Keep everything you remove, it is worth something to the concourse guys.

    Thanks Larry

    That's what I have now, one line from the carb to the vacuum advance.

    What size NPT is in the manifold? My kit came with a 3/8 x 1/4 bushing.

    1/2 NPT.

    Question on the oil pressure tee you added. I see you used an all female NPT tee, with a close nipple into the block.

    How did you tighten that tee in there being so close to the block?

    That is not mine, I just used the picture as an example. There is no correct way to do this, there are many ways. the opening in the block is 1/4 NPT. Use a bushing to reduce that down to 1/8 NPT, then use a right angle with one male 1/8, and 2 female 1/8 NPT. You'll be able to make it close to the block and get it oriented correctly. You don't have to do it the way the picture illustrates, build your own.
