I'm in the process of swapping the clock for a mechanical oil pressure gauge and I'm not 100% sure how to hook it up at the engine and still retain the warning light. The picture below is what I have now and I'm not sure if this is factory stock or not as this engine has been rebuilt a couple times by the PO.
Any help you could give regarding procedures, pipe sizes, etc. would again be appreciated.
Thanks!

Relax, all right? My old man is a television repairman, he's got this ultimate set of tools. I can fix it.
