it may not be that easy since the hybrid uses an electric compressor instead of a belt driven compressor. |

The generic atc upgrade on most cars requires the following
1. ATC head 2. ATC plugs 3. NEW wiring harness (remove dash and replace every single plug with one main harness, radio, blower motor plugs, etc.. 4. New auto blower module control (its a small module about as big as a hard drive) 5. sun sensor (most cars have this already for auto headlights) 6. The blower control module will have different plugs too so that plug is needed also Thats the generic idea, and what im doing to my intrepid. I only have to do the harness and module since i have the rest already in it... still its a pain to remove the entire dashboard to do this... involves removal of the seats. Thats why im gonna stick with the ghetto MTC> LOL for the civic. |

Guys, do I understand well that the non-hybrid Civics sold in the US do not have any ACC?! It is strange as it is standard equipment even on the lowest trim petrols (we have LS and ES trims) here in Eastern Europe
 At least this means that you do not need D-CAN! The ACC is proven working with the petrol 1.8L engine. I do not really want to take my car apart to check connectors etc. but am willing to help you however I can to have this fixed. Like this: http://index.hu/cikkepek/totalcar/te...csedan_021.jpg http://index.hu/cikkepek/totalcar/te...csedan_028.jpg Cheers / HUHarvey Last edited by HUHarvey; 07-21-2007 at 08:59 AM. |

However, I DON'T think that assuming the ACC unit (from a CSX or a Hybrid) is compatible with the other USDM Civic's is expecting a lot. It would simply mean finding the correct 'molex' type connector, and then moving the wires with their pins from the original connector to the new one. Or less elegant, but equally as effective, simply removing the wires with their pins from the old connector and manually pushing each one onto the correct corresponding post in the ACC unit. techinfo.honda.com will provide the wire pin-out for BOTH the CSX/Hybrid's connector, as well as the pin-out assignment positions in the orignal USDM Civic's connector. I'm fairly confident this will be a fairly straight forward mod, but I have so little free-time as it is, and I already had Tinting, Signal Mirrors, Leather Interior, Rear Spoiler, and Wheel mods planned for my sweet, sweet Civic GX natural gas ride! (You should see the smile on my face every time I fill up my car, and see the total sale ring up as $3.80!!) Plus I HATE that techinfo.honda.com charges me freaking $20 for a lousy 3 day access!!! Like what we were all doing HERE in the Sienna forums, when we were retro'ing OEM NAVI's into our vans and attaching all the goodies like backup cameras, speed sensors, and microphones, etc... |

rewiring everything would take forever. PLus theres a blower module that is usually different in the manual vs auto climate which has to be replaced.
Splicing etc can cause issues and blown fuses or other damage. Im going to look into getting the entire CSX harness. |

Not sure we're on the same wave length here. You're not REWIREING everything, you simply routing 32 wires to the correct pins. (Plus what kind of attitude is that comming from someone who along with his roomate used a meter to logic trace harness pins in the past??) And not sure what the blower module would have to do with anything, the ACC unit is fully 'autonomous', by which I mean it's not communicating with a climate ECU, and the ECU does all the work. The ACC 'IS' the Climate ECU. The only thing the knobs are on the manual unit is 'potentiometers'. What's comming out of the back of the manual unit, is going to be identical to whats comming out of the back of the ACC unit. There are only going to be additional pins to handle the temp and sun sensors. There's not going to be any splicing. No wires are being cut. I'm simply moving the existing terminals to a new connector. (Outside of Plug-n-Play, it don't get much easier then that!). There's not going to be a problem with blown fuses or other damage. I'm simply going to move the wires from my stock connector, into the new connector that fits the back of the ACC unit, and add in the temp and sun sensors that I'll add. The guy on the first post in this thread says he complied a 'data dump' with all the schematics and info he got off of the techinfo website. His link to them is dead now, but I'll see if he still has them so I don't have to spend the $30 on access to the info. I'll update you on what I find. |

Im not sure of the civic but on my intrepid its like that. The climate control uses the sun sensor which the civic doesnt have, a different (looks identical) blower module (which is a small alloy piece controller thing, not the actual fan motor) and a new harness which yes you could rewire instead but its easier just to get a new one. When i say rewire i mean the acc related wires and 32 wires is a lot. 4 -10 wires ok i could manage but 32 is too much. Its not the same wires trust me.... the acc head is not standalone otherwise it would use the exact same plugs, you think honda doesnt want to make their life easy. Whenever anything is plug and play the plugs are usually teh same with very slight differences. But when pins are not there or too many wires are present u run into issues. The safest way is with a complete new harness which will have some useless things like the radio which u already have but its only around 100-200$ and it saves the hassle of splitting wires etc... Im not sure why the blower module needs to be replaced on some cars, maybe not the civic but its best to assume the worst. Let us know how it works out, if its rewiring we may be able to come up with a kit of some sort to convert MTC to acc... maybe honda uses a crappier version which is just standalone. |
