These are the repinning/splicing that is required to swap a '165 ECM in
for an '870.  All pins/info was taken from:

A11 (MAT)				C12 (MAT)
D2  (Fan Ctrl)				C1  (Fan Ctrl)
D8  (EGR Diag)				C15 (EGR Diag)
B4  (EST Ctrl)				D4  (EST Ctrl)
D13 (TPS Gnd)				D2  (TPS/CTS/MAT Gnd) ^*
C9  (Fan Reqst)				D11 (A/C Pres. Fan Reqst) %*%
B11 (MAF)				B12 (MAF)
D12 (MAT/MAF Analog Gnd)		A11 (MAF Analog Gnd) ^*
D15 (Inj 2,4,6,8 "B") (1of2)		D16 (Inj 2,4,6,8 "B") ^*
D14 (Inj 1,3,5,7 "A") (1of2)		D15 (Inj 1,3,5,7 "B") ^*

Splicing
---------------------------------------------------------------------
C15 splice D15 (Inj 2,4,6,8 "B")(2of2)	D16 (Inj 2,4,6,8 "B") (new D16, old D15)
D16 splice D14 (Inj 1,3,5,7 "A")(2of2)	D15 (Inj 1,3,5,7 "B") (new D15, old D14)

Maf Burnoff relay -  pin A		MAS connector pin D
  and MAF Pwr relay - pin D

Maf Burnoff relay -  pin C		B1 (12V and oil sw override)
  and MAF Burnoff relay - pin E
  and MAF Pwr relay - pin E

MAF Pwr relay - pin A			MAS connector pin F
MAF Pwr relay - pin B			D3 (Ground)
MAF Pwr relay - pin C			B2 (FP signal)


New hookup
----------------------------------------------------------------------
		D12 goes to Maf Burnoff relay - pin B

Removal (unused)
----------------------------------------------------------------------
C12 remove

----------------------------------------------------------------------

ECM pinouts are listed on the connector harness and also shown in the
ECM wiring diagrams.

MAS ('85 Burn off module) pin letters should be on the MAS connector harness.

MAF Pwr and Burnoff relay pin letters are on the stock harness connectors
	and possibly on some OEM and aftermarket relays.

^* NOTE: '85 Ybody (vette) may have these swapped.. Check your app..
	(Thanks to Philippe Maier for catching this!)

%*%  Depending on what '165 bin file you use, be sure to check that it's
	programmed for the correct A/C pressure switch in your application, 		either normally-open (N/O) or normally-closed (N/C).  An incorrect
	setting will cause the Rad. Fan to run continuously.
