Way to bypass a relay?

[Ky1200]

I have a New Holland 1920 tractor that needs a relay, New holland part #SBA385230220. I was floored when the price for this little piece is $174.00. Is there any workaround? Even if it's a larger relay or ? ?? Crazy to have to pay that much just to start the tractor by the key switch.....
thanks for any info

Usually a relay is used to switch a high power/amperage circuit with low voltage. So bypassing is not easy. If it your Starter Relay it is not that expensive

Have you tried going to the local parts houses with the relay in hand, and see it they can match it up. A lot of the factory parts are a bit very over priced. I get most of my miscellaneous engine related parts, not as TYM branded parts, but asking the guys at the parts house for what will work on the Mitsubishi S3L, engine in the tractor.

Try Digikey or Dell electrical. I bet they will have exactly what you want at a much better price. Had the same issue with my AC relay's for my Kubota M series. Kubota wanted over a hundred bucks each (takes 2) and Digikey had them for 10 bucks each. Same exact relay, same catalog number, exactly the same. I even bought a couple extra and gave them to my dealer so he could install them as the AC relays are prone to failure on the Kubby cab models.

I have zero issues buying OEM so long as the price is reasonable. When it's stupid, I look elsewhere. Just match the catalog number on the relay. Relay's, like bearings all have a specific identifier number on them.

Entering the part number and New Holland in the Amazon search gets one for $45. But with a bit of wiring you can make most any starter relay work. But a relay base and new relay may be close to the $45.

Basically a four pin relay has a ground, a control feed, power in, and power out. Unless space is at a premium, you can wire in any relay with high enough amperage capacity.

You can replace that relay with a standard 12 volt automotive relay, but you also need to replace the socket with one for the standard auto relay. Get a std relay with a harness. This is less than $10 on Amazon.

You need to remove the wire pigtails from the new relay socket. Then remove the wires from you tractor's relay socket and you then insert the tractor's wires into the new socket. You need to get the tractor's wires in the correct space on the new socket. If I recall correctly, the original relay had a wiring diagram on it, as do most auto relays so identifying where the each wire goes should be straight forward.

Use a very small flat blade screwdriver to remove the wire's from the connectors.

This is what I did on my 1520 when that relay failed several years ago.

As toot77 said. Get a Bosch relay off Amazon, match the pinouts and you're good to go, $174 for a simple relay is ridiculous.
I f you don't want to modify the wiring harness, add some male spade ends to the new plug and plug it in to where the relay went.
Here's the pinout diagram so the coil connections would go to 85 and 86 on the new one, common would go to 30 and NO would go to 87

this looks like exactly what I will be doing, thank you

Thanks to all who took the time to answer... really appreciated and it will solve my question easily.... I'm going with tool77 and mrmikey's posts ..
thanks

Be careful with installing a Bosch cube style automotive relay. They are typically rated at 30-Amps.

The starter will pull 100 to 300-amps. And, could easily burn out the contacts on a standard automotive relay.

Look for a starter relay, with a high enough Amp capacity to handle your starter.

This, or something similar. https://www.amazon.com/gp/aw/d/B08F...d_r=f2416631-751a-4bfa-b069-9fb584d0980b&th=1
