i am doing a 4.3 vortec swap into a 1986 22r 4x4 truck. i had an 85' 4.3 rebuilt with vortec heads, murine 4 barrel intake, 500 edlebrock carb, using old school non vac. advance distributer with coil on cap and msd 6al box. fuel cell and inline holley red fuel pump. using stock running gear mated to motor using advance adapters bell housing kit. i am running everything as easy as possable. using a tci mini starter (for a small block chevy), 350 2 wire chevy alt., 350 short nose water pump, 350 small block powersteering pump/ toyota ifs steering box ( modified-box high press. hose to fit threads into pump). also running mechanical oil press. and temp gauges. Now what i am not sure of......... how do i wire the motor? my thoughts are can i wire it using power leads that originaly went to the motor and do away with what is not needed. meaning..... what ran to toyota starter run to chevy starter, what ran to toyota distributer run to chevy dist., what ran to toyota alt. run to chevy alt. and so on and doing away with what i don't need. there for using factory wiring to run the motor and all my ignition, lights, and so on. any info, suggestions, help, or direction is greatfully appriciated

 

frit questin iam going to ask is this truck your daily driver?

if so better get a anoter car to drive this is not a weekend project if you dont haveall the right parts and help

and what specificly are you have trouble wiring

ive done the carb 4.3 swap so i can help

 

i am thinking about a swap like this on my 88. keep us posted with pics and details. Thanks

 

1st, no. it is just a wheeling toy. 2nd i am not a wiring genious. just dont know where to start.... rip all the wiring out and start from scratch or try to use what i have. meaning, can i use the stock wiring harness to run this motor. the motor/trans/transfercase are all in/ the dist. alt. starter, water pump, power steering, exhaust manifolds, carb/intake, fuel system are all installed. wiring is my next step, where do i start?

 

are you usin stock manual tranny or chevy tranny

 

manual toyota tranny and toyota transfer case, using advance adapters bell housing kit, 153 tooth 10.5" small block flywheel and press. plate with centerforce clutch disk and land cruiser slave cylinder supplied in bell housing kit

 

Your on the right track !. First what tranny are you going to use? 22R so your not fuel injected ? Is the 4.3 TBI, TPI or CPI ? Do you have smog to deal with ? Wiring is easy if you have the donor vehicle. Be prepared for adapters, exhaust, VSS, minor electrical, driveshaft mods, x-case mods, and cross-member mods. I have wiring and info on it all, so just ask.

 

the motor/trans/transfer case are all in (stock trans and transfer case). transfer case in stock location so the cross member went right back to stock location. used 2" body lift to clearance bellhousing and shifters work using orig. placement. using carb... no fuel injection. using modified stock tubular exhaust manifolds that are on the motor and clear as needed

 

to run the motor you will only need three wires one to your fule pump that come on ing hot not acc, ignition hot one to the fule pump and you will need to install a regulator for the fule and you need another ign hot source for your hei distributer and thats pretty much it all but your starter just go to your relay and run a wire from the realy to the chevy starter and as for the alt get a plug for the chevy alt and take it to the alt shop let them wire that up its kinda tricky


any other questions i am happy to help wish i woulds have had some doing mine but mine was trail and error and nobody in my town want to help put a 4.3 in a toyota so i was all one my lone some the whole swap

 

i swaped out the factory toyota tank for a fuel cell with a holey red pump, i can wire that. i ran a msd 6 al box for the ign. i need a to run that to a wire that comes on with the key (or toggle). i have a factory chevy plug ofr the alt. what i really need is a way to patch the starter into the toyota wiring

 

i want to be able to get in and turn the flip a switch for the fuel pump and hit the key. how do i patch into the toyota wiring to get it to work correctly

 

very simple the starter realy should be near the passenger kick panel find the wire that is hot when the key is in start position and run that wire to chevy starter

 

is that useing the factory toyota wire harness under the hood from the battery to the starter and so on, or go to a parts store and buy new battery cables?

 

you i just used stock cables rip the entier toyota engine wireing harness out after you unplug it from the computer and you can get a few 12volt sources from left over plugins that go through the chassie

 

do i need to use the relays next to the battery box at all, i know that goes right to the battery

 

i kept mie only because in the future it would make a good relay box for lights and such

 

ok so i have a 85 toyota PU that has a 95 4.3L vortec motor in it and it has no power steering what all do i need to get power steering in my truck??? need help toyoa on 38 inch swammpers not fun with no power steering
