Default gauge problem!!

Hello, got a 78 corvette and the bottom three guages dont work, have the oil pressure instead of the clock. Have fitted new circuit board..
The top guages work and light up but the bottom three dont do anything and dont light up. I noticed there is like a three prong on the back of the oil pressure guage is there a plug for that as it would be missing or if Someone could take a photo of what to look for and to see if I have mounted the guages corrctly on the back

Thanks

I'm assuming you mean the oil teperature gauge. Yes there was a plug for that. If your wiring harness does not have it, looking at it from the back the right quick connect is "key on 12 V", the center is ground and the left is the oil temp sender. You may want to put a piece of electrical tape over that flap on the new flex circuit. That would have attached to the clock to provide power, and it is not used when there's an oil temp gauge.
