We have a spare set of contacts on our oil pressure sender to drive a low oil pressure LED, we therefore are using that change to drive Hobbs when oil pressure is high enough to turn off the low oil pressure LED.
Art did a beautiful job soldering everything together.
Then Alan took over and JB KWIKed the relay and tywrap clip to Hobbs. Then put a mini fillet of Aeropoxy / 30 minute around relay and clip and then laid up 3 thin layers of model aeroplane cloth over clip.
Hard to see but red wire is soldered to Hobbs and has a dab of JB KWIK to act as a strain relief so there is no movement at solder joint.
