Just double checking, (also useful documentation for anyone else trying this out), like this? https://www.ebay.co.uk/itm/323298227155
Possibly. I wish they'd put part numbers on these ads, so you know what fits what. That's the kind of thing, tho'
You need the 9 pin relay base for the tachometric relay. I use the KAE relay with integral fuse they were about £24 but seem to be in short supply.
It'll be interesting to see which one you've got. Snotty can tell us if it has a timer circuit in it for priming
Cheat and set up a 'priming' signal for for a relay off the alternator signal taken from the reverse light .. . Sent from my SM-G930F using Tapatalk
Should do the trick The earlier ones seem much of a muchness. As before, I can't see how these can provide an initial prime, as there's nothing in them that would do it, apart from a few spurious pulses from the coil (which may not be there if you've got a fancy dissy). I've tried the KAE one, and there's no initial prime.
I'll have to see if my Pertronix causes a glitch on the coil to prime the pump or not. Otherwise, as @Deefer66 says I can use the signal off one of the idiot lights to open the solenoid and prime the pump.
Issue with that is you won't get a signal from alt or oil pressure switch...until the engine's started. Which it won't if there's no fuel.
