Will this work on a 1985 four runner?

jeez...every three months the same question...It'll work great if you're intent is to to set your vehicle on fire and collect the insurance...IT'S GARBAGE!! ...the wire is criminally undersized for the application...it should be 14-16g but it's only 22g ...this can cause it to overheat, melt the insulation and start a fire.....

Did not come with manual, where can I find it online?

Dear customer, Pretty sorry for this trouble. Kindly please send email to kaslight2@outlook.com, we will send you the manual accordingly

Will this work on an 87 toyota pickup ?

I installed it on my 88 Toyota pickup 2wd. The high beam did not work. The high beam relay would work but would not turn the high beam on. Found the wiring on load side of the relay was wired wrong so I had to pull the wires out and relocate them. High and low work good now. If the relays work, but won't turn the lights on, the issue is on the load side. Check the wiring on the relays.

Will this work on a 93 chevy blazer if not what harness would?

I dont know alot about Chevy blazer but work great in my 93 XJ. I dont see why not,
