New Temp Guage Hookup - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just picked up an '84 Blazer with the 305. I'm putting in an aftermarket temp guage...the light isn't cutting it. Where do I install the probe? The last time I insstalled one it was on a '78 with a 350. The sending unit was in the drivers side head. On this '84 there is only a plug with a square insert on the drivers side head. It almost looks like a 3/8" socket opening, but it's not(almost like a rear diff plug). What do I use to get this plug out? I only have a limited run of the capilary tube that the guage came with. So I it looks like it has to be some location on the drivers side of the engine.

Thanks for the info...
