Alain - I am going up to the boat tonight and will try to take some photos. I bought the relay kit at a local DC motor shop Northstar Auto Electric, 105 W Main St, Macedon, NY 14502 Starter relay circuit added: Blue - 12v +; Yellow – Solenoid screw; Black – 12v- (gnd); White – switch circuit

Hi Steve,
I'm in Oakville, Ontario across you on the Ontario lake. I have a same problem with my 4jh2e. I saw your suggestion to tackle this issue by installing a relay. Couls you please let me know the name of the relay you have and how you installed it.
Thank you very much.
Alain
