Tpi swap please help identify ECM pinouts.

[Lord Kebson]

Hello everybody.
I bought 1984 Cutlass supreme without an engine ECM harness.
I'm in the middle of 5.7 TPI Speed density swap and I'm trying to figure out some pinouts.
The connector is on the passenger side where ECU was.
I need
12V (always hot)
Ignition switched on
Check engine light
Break pedal switch for lockup
A/c on
But best if someone could name them all.
Thank a Lot



One side is:
A) brown wire
B) orange wire
c) white/green wire
D) - (empty pin)
E) white black
F) pink/black wire
G) - (empty pin)
H) light brown/black wire

Another side:

J) - (empty pin)
K) brown wire
L) - (empty pin)
M) black/white wire
N) orange/ black wire
P) purple wire
R) - (empty pin)

I'd have to look when I get home. If interested, I have a Painless TPI speed density standalone harness, ECM, custom chip burned by TPIS (just need to send it to them for a reflash), even a good set of SVO injectors. I also have a Holley stealthram intake (non vortec heads) with a BBK 1000cfm TB, dizzy with extra module, GM dual connector coil, and I'm sure a few other things. Oh, a new Comp hydraulic cam and lifters too. This was my Cutlass before going LS...

Please have a look when you have spear moment as I stuck with these connectors as someone chopped harness with the axe.
BTW you setup looks amazing very clean,.

Will do, and thanks....that setup is for sale. There is one person interested, but I'll let ya know. I have an LS in my Cutlass now, the TPI setup is in boxes.

Thank you for letting me know, I do have the wiring harness, air filters with custom intake not for sale?

Intake will be for sale at some point. I'm using part of it as a temporary intake on my LS...

Thank you very much for speed density pinouts, this is very helpful.
I need exactly the same thing but for the connector from photos, I uploaded.
I can't find anything for that connector.

I've been searching and searching and I think I have found it 😀

Partly solved, but if anyone could confirm this that would be great!
