Thanks man. I cant wait to start this project.Just stopping in to validate Peewee's water temp sender wiring. The MA70 works just fine with the stock temp sender from the 1UZ. The 1UZ temp sender's resistance is only a little off at the high end which is nothing that would really appear in the gauge movement all that much. Wiring is straight forward, yellow-green connection and earth the brown wire to the block. Once I figured this out I went from having the temp gauge go from zero to red hot at the first sign of the engine heating up to working normally. You can do a search on my thread since I think I documented the 1UZ and 7M senders there as well as the wiring issue. You can also check out my site, http://1uzsupra.com for some wiring information between the pre-89 MA70 wiring and 1UZ wiring. All of my dash gauges, including the CEL light (which should be the first thing wired since it is so helpful in troubleshooting) work.
