syclone engine wiring harness

[jasonpickett]

I need ll of the wiring harnesses from the firewall plug forward. I was wondering if I can get one from a s10 4x4. Also would anyone know if it would have the vss plug and everything with it. Please any info would be appreciated.

Thanks,
Jason

How much of whats in your engine bay will you find in a 4x4 S10? Dont expect it to work without modifications. Maybe you can modify it yourself. Add the needed circuits and such. Think so?

I have used s10 harnesses for both my swaps. Most First gens use mechanical speedos though

Re: syclone engine wiring harness

It appears you need the "forward lamp harness". This is pretty much the same for all S/T series from 1983-1994. There are subtile differences regarding connector styles, and ABS or 4WAL wiring, but almost all of them can be adapted to the year you're working with.

For an LSx swap you will need the "trunk" of the engine harness that plugs into the bulkhead connector. This portion of the engine harness contains the following circuits that need to be integrated into the LSx harness or engine.

Battery Feed to truck (2 red #10)
Ignition on with key (pnk 12ga)
Starter (pur 12 ga)
Oil press gauge. (tan)
Temperature Gauge (dk green)
Windshield Wiper Motor (4 wires to plug)
w/Washer pump (Some years. And other years this is in fwd lamp harness).
Alternator excitation. (pnk/wht)
Fuel pump to fuel pump. (grey)
ECM B
VSS (pur and grn twisted pair)
There may be others. These are off the top of my head.

There are also some connections to the C101 / C212 connector at the RH side of the IP harness.
there was a recent thread on these connections. Try "C101".

I am going to run standalone. I mainly need it to plug into the firewall, work the lights, and possibly the vss. I want to run a tci tcu later on I have to check to see if the vss splices into the tci tcu or still runs off the factory harness.
