I finished my suspension so last night I removed the factory pcm and am in the process of removing the engine control harness. With luck I won't have to pull the intake but we'll see.

Looks like I need to wire up:
-coils
-injectors
-tps
-iac
-iat
-cam sensor
-crank sensor
-starter
-alternator
-fans
-tach

I have the FAST mounted on passenger side so the eDIST and crank box will sit next to it.

 

Thats a whole lot of wiring to do. Just be glad you aren't colorblind like me, wiring is a weak point for me.

what are you doing for gauges?
to bad fast doesnt make a gauge adapter.

 

coolant will still work
oil will still work
gas would work if mine worked
losing speedo
losing tach

i have 5" tach will use that for now.

 

It's not too bad once you get started. Just time comsuming...

 

What alternator are you using Chris?

I guess my 98 stuff is different from the other years, so that's one thing I need to stay on top of.

 

I'm using a stock LS1 F body alternator.
The only thing differentiating your 98 alt. setup from the 99+ is the small wire. The small wire needs a 500KOHM resistor inline, then be hooked to 12+ switched. your 98 setup does the resistance with a light in the gauge cluster, the 99+ does it with the PCM.

So the only thing you need to change possibly is make sure the 12V small wire gets a resistor inline, either with a resistor or a light bulb.

 

Kurt and Chris,

John and I are wiring up his standalone harness and many of the connectors of the FAST are different than the factory sensors like the IAC, TPS, CAM POS, etc...

Does fast supply adapters to connect the fast plugs to the factory sensors or should we splice our own.

I suppose caspers electronics has all of these connectors in stock but I would think that FAST would supply them as well. What did you guys do for your setups?

Thanks.

 

As a follow up, I have the pcm and engine harness out. I had to remove the intake to get to the stuff in the back.

Right now looks like it will go like this...

-coils, need to make the eDIST harness and wire that, it came with connectors, half of the wires go to one side, half to the other
-injectors, already came with FAST harness for them
-tps, need to wire in ls1 connector
-iac, need to wire in ls1 connector
-iat, already wired in by z8's
-cam sensor, need to wire in ls1 connector
-crank sensor, need to wire in the FAST crank box into an ls1 connector
-starter, need to figure out how to do this because when I removed harness I had to remove a brown wire (hot) off the starter
-alternator, 98's are 12 volt supposedly and whistler and kurt seem to have the best handle on this
-fans, wire them into FAST
-tach, seems that I can wire it into a eDIST output
-map, 3 bar already done by z8's
-FAST w/b, already done by z8's

Kurt I am going to try to call you within the hour in case you see this thread.

 

I cut the IAC TPS and cooling fan plugs from a stock harness, left about 2 inches of wire attatched and soldered them to the FAST harness. I heard FAST can give you adapters for those though.

The LS1 cam sensor plug should have come with your EDist box.

 

I was told AEM is coming out with a plug and play system for our cars. They just came out with it for mustangs and allegedly have an LS1 prototype out. Im going to wait it out and see what they come up with. It would be alot less work then the fast system.

 

Whistler are you running an eDIST?

Can I just wire the cam sensor into the fast connector, or does it also go into the eDIST?

I'm ready to cut and change:
IAC
TPS
Cam
Crank - partially done, 3 of the 7 wires
IAT - done
Coolant - done
MAP - done
W/B - done
Starter - remove wire from harness, it has it's own plug from the factory, no modding needed
Alternator -
Oil Pressure - Stripped wire out of harness, will repin it into the factory harness, not sure where to ground it

 

Notes to myself before I forget:

IAC- just wire in the gm connector, need FAST pinout for IAC wires
IAT- done
TPS- wire in gm connector, I don't think I need FAST piniouts only 3 wires
Coolant- done
Cam- won't be using FAST wires from main harness, cam sensor wires into eDIST only
Crank- won't be using FAST wires from the main haness, two of the crank wires go to eDISt; red is power; black is ground; yellow, yellow/black and green go into factory crank sensor
eDIST- need to check with George on the different models, don't have the LED one
Starter- stripped it out of main harness, need to run the wire to the BCM harness
Oil Pressure- Need to trial route that to dash harness on passenger side, but where to ground it?
Coolant gauge?
Tach? C15 piniout on eDIST, can I split it and also send it to the cluster?

 

Updated notes to myself:

IAC- just wire in the gm connector, need FAST pinout for IAC wires

IAT- done

TPS- wire in gm connector, I don't think I need FAST piniouts only 3 wires

Coolant- done

Cam- cam sensor wires into eDIST only

Crank- crank sensor wires (3) go into decoder box; 2 wires out of decoder box go into 4 pin connector per George @ FAST; will not use main harness connector

eDIST- I have an older box per George; white wire goes from eDIST to FAST and is the cam signal

Starter- stripped it out of main harness, need to run the wire to the BCM harness

Oil Pressure- Need to trial route that to dash harness on passenger side, but where to ground it?

Coolant gauge?

Tach? C15 piniout on eDIST, can I split it and also send it to the cluster?

Alternator- 98 is supposed to be 12 volt, 99-02 is different; not sure how it works

Damn John, you are cutting awfully close for the N vs S shootout. You going to make it in time ya think?

 

I think I am actually. If the FAST had been a plug'n play deal I would have finished it Friday night.

 

Looks like quite the rats nest John. Let me know when you plan on making the maiden voyage in it at the track I gotta see it.

 

It's not really a rat's nest, the wires draped over the fender are all labeled. The issue for me has been the wiring of the cam and crank sensors and the role of the eDIST. I got that all cleared up today.
