Really basic relay question
I'm going through and doing easy refreshes to rule out some of the current goofiness with my S4: new NBO2 sensor, new engine ground strap, and replacing relays. Using the chart provided by @ROG100 and @Alan (https://cdn.shopify.com/s/files/1/16...82372723095894), it looks like there are 8 relays which are interchangeable.
My question is, 7 of those relays have the same part number, but the LH relay (#25/XXV) has a different part number. I bought a number of the other PN; can I put one of those into the LH place, or is there some subtlety that I'm missing? Things are already sort of messed up as it is, I don't want to compound things.
Thanks

The LH relay is also used as a fuse tester so it has a different part number. But it can be replaced by a 53B.

As Roger says - Any of the 53B relays can be replaced with the fuse tester relay and vice versa - functionally the relay parts are the same.

It seems my car had already had a non-fuse tester relay replacement, so I didn't even know that was a thing.
Thanks, gents.
