1st gen 4r alternator/regulator harness questions

Any electrical whizzes in here can give me some information on why/if the sense wire needs to be a certain gauge? Apparently the highlighted wire off the regulator is spliced into the charging wire and reads battery voltage. Old alternator managed to melt the harness and i gotta rebuild. I'm sending a new larger 4ga wire to charge the battery from the alt. Ive got a set of connectors that will happily fit 14-20ga wire for the regulator harness. But the sense wire is a 12ga, it wont fit. It's just a sense wire though, should be able to hit battery voltage without issues right?

'86 22-RE engine failure pre-diagnosis

Before i go digging into the bottom end i wanna see your predictions. In the time leading up to engine failure i've had a smoothe running engine. No evidence of knock anywhere through the normal operating range. Sudden knock appeared at 3k rpm on highway going 65, then uncle rodney came knocking. Bearing is probably spun, engine is now locked. Oil pressure read normal as well as coolant temps, all sensors recently tested. Engine is sitting at 160k miles. Timimg, guides, oil, and water pump all have 10k on them. What do you think is the most probable cause for the crankshaft bearing failure?

Disc brake conversion?

Just picked my '86 up a few days ago so Im new to 4runners. Brakes are awful on this thing and leaking from that load sensing valve-proportioning valve line at the rear. Ive seen the LCE rear disc conversion kit but i dont want to have to get new wheels if i can avoid it. I like my OEM look. Which sites are we shopping for performance parts?
