How many are using the factory amp meter

I have hundreds of thousands of miles on an original amp meter installation.
But it seems like I hard wired the power feed though the bulkhead disconnect on that one.
How many times do I really need to take the connector off anyway?
And I don’t have AC and rarely need high beams.

Off topic.
I hate gremlins which I feel this is. Last week she developed a “miss” at idle and under acceleration to a point. Getting the car good and warm make it show up. Someone may remember my last problem of this sort about two years ago.:wink:
I’ve got some used ECUs. But on a lark I picked up a new one at O’ Reilly’s yesterday just to try it. Didn’t even work out of the box. Chinese stuff.
Guess I better pull the dist. cap. Geeze. How long has that thing been on? It's the good stuff. Brass terminals though.
