Weber carb install question.

[Swbtwo]

I have a Weber 32/36 DGEV on order. I have the wiring harness out of the engine compartment for unrelated issues and wonder what’s the best of the numerous old carb related circuits to use for the new electric choke?

For reference, it’s an 1982 4.2 with an HEI distributor and all of the computer/smog related equipment removed.

Suggest you use a relay activated by the ignition via an oil pressure switch. Holley sells parts for this - and likely has a tech note on their site. Their OPS may not need a relay.

I very much appreciate the help, sorry if I’m wearing out my welcome. With a carb solenoid and a choke switch circuit already available, I assumed most people would use one of those two. It’s not addressed in the instructions beyond “connect original choke wire”. Come to think of it, cutting out that switch and going straight to the “choke feed” seems simple enough.

While I have you, just to demonstrate how far from shore I am on the topic, what’s OPS stand for? Google was no help.

Oil Pressure Switch - sorry my bad - one is supposed to introduce acronyms like this: oil pressure switch (OPS). I thought it would be obvious from the context.

You need to connect it to the ignition somehow, so the choke element starts heating as the engine warms up. The OPS is in there to stop the choke from opening if the key is on and the engine is not running. A relay takes the current load from the choke element off of whatever circuit triggers the choke.

OPS is crystal clear in retrospect.

It’s not in use with the computer gone (oil sensor next to it still is) but I see no reason to not use it for this.

Thanks again.
