Using both senders is an interesting idea. I have always used the GM senders that the ECU read for engine/tranny function and then in a separate isolated harness use the Toyota senders in the GM block to run just the Toy gauges. The last project I mated everything into 1 harness but it was quite a bit more involved. Great work by the way. I have a new project that I am thinking about, just not sure when or how to do it yet.
