looks like you are making good progress, this is where the fun is because everything you do is the last time you do it, no more test fit assembly then blow it back apart. things are DONE done.
I went the stepper route on the 47 and the 49, looked amazing.

mine went to the original s10 cluster that I hid behind the dash, but you could do it like henry did too with aftermarket gauges. on the high beam/turn signal thing, on the 47 I put the lights on the steeering cover, on the 49 I drilled them into the speedo face.
I am getting to the point though that I will just order some custom made to work with the S10 harness from now on. figuring out hours in the shop, it costs less! there is a company I cant remember the name off hand that makes some killer gauges and you essentially tell them what you want and what the senders are. I am jonesing to use them on the next 49 I am doing.
