been working on wiring for EATC swap and need to know if the harness is modular construction If there are any ford Techs out there please look at what I have come up with so far and give me some feed back on harness.

First
I cross referanced with 2000 expedtion harness and wonder if anyone can get part numbers for the following causal harness numbers 18b518 and 14401

second looks like truck will have to be refitted with
(1)blower speed controller to replace resister type.(c282)
(2)need new blend door actuator
(3) need sunlight sensor
(4) need in car temp sensor and maybe new radio dash surround to house it
(5) my truck already has ambient temp sensor just have to pick up sensor from harness

ETAC connector conversion Rough draft! INFORMATIONAL ONLY

4-470- SENSOR INPUT GROUND ?

11-348-VT:A/C CONPRESSOR CUTOFF -> *C217 PIN 3
12 N/A
13-250-DG:BLEND DOOR ACT MOTOR DRIVE HEAT ->C229 PIN 7
14-19-LB/RD:INSTRMENT PANEL LIGHT FEED ?
21-790- WH/OG: IN CAR TEMP SENSOR INPUT
22-575-YE/BK: RELAY TO AUX CONTROL(DUAL ZONE) N/A
23-184-TN/OG: BLOWER CONTROL INPUT ->C282 PIN 3
24 N/A
25 n/A
26-DB/LG:BLEND DOOR ACTUATOR DRIVE COOL -> C229 PIN 8

my theory is that if the harness is of modular design I can swap out the harness at one of the in line connector faces to come up with the proper harness connectors to the newly installed modules

 

Does anyone have any updates (or a how-to maybe)?

 

Since auto climate control was offered as standard equipment on the '03 Screw Lariat, you could check the
Ford parts catalog for the part numbers that you would need. Since I'm not a hvac expert, I wouldn't be able to
tell you what actual parts you would need for a conversion.
But it would be a good place to start.
