You might have to hardwire the Tach between the DB3 and the 4806. Depends on what Note 1 says. Just so we don't overlook things... The DB3 must be flashed with the 4.03 NISS08 firmware, presently at Version 1.20. Has this been done? When you did the DB3 to vehicle programming after making all the connections, did it follow the steps and indications exactly? The DB3 should handle the locks and alarm plus the transponder bypass funcions. It should also supply the Viper with the Brake, Tach and Hood Pin signals via D2D. Do the door locks work via the Viper remotes?Soldering is fun!

Kreg, thank you for the information, I will check these wirings and see if I missed one from my initial hard wiring. The car locks and unlocks like normal; during the programming to vehicle, the flashing did not occur like it said when I performed the steps (it was very simple but I was not convinced one of the steps went through). It is possible that it did not through because my wiring was not correct or was not complete. I believe there may be a wiring that I did not connect from the list you supplied, I will verify and report.Honda Accord 2008 EX-L 2.4 S

Kreg, I checked my wiring really quick and found that I used the heavy gage remote start 8-pin wires #3 & #5 but I should have used the #1 Ignition 2 from the 24-pin connector, same for #21 Starter output, in this case the polarities will match the car's. This may have been the reason as to why I was puzzled that such heavy gage wires from the 8-pin would need to be connected to the small wires at the BCM. I will rewire per your instructions and report, since it is snowing, I may have to report at a later time. Thank you for your help.Honda Accord 2008 EX-L 2.4 S

Kreg, I verified the wiring and everything looks good, I initially thought that I had used the heavy gage wires for the ones that have the diode but that was not the case. I verified the wiring and everything looks correct. I remember that the module did not flash the green light, is there a way to restart the programming side without flashing it to be able to follow the module programming again? I don't have access to reflash as the seller did that for me when he sold the unit to me. If I reset the DB3 module (if possible) will it loose the flash to the car? I think this is a flashing issue at this point, door lock/unlock and trunk release work, the only thing that is not working is the remote start, it looks like it tries to start, activates the accessories, the module receives the signal, flashes orange and red momentarily and then flashes green for maybe 5 seconds and then turns off. The sequence of DB3 flashes when remote start button is pressed: 1. 3x green flahes. 2. 3x yellow and red flashes (interchangeably) 3. Multiple green rapid flashes, then goes back to green slow flashing and tries again 3 more times before it stops. In the process of the rapid flashes I get the I-Key System Error: See Owner's Manual. The vehicle does not crank at all. Here is the module programming instruction. Honda Accord 2008 EX-L 2.4 S

Unfortunately, I'm not a DEI guy but you can do a "Soft Reset" as shown at the top of Page 15. This will get the DB3 ready to start the vehicle programming process again from the beginning. It will not affect the 403.NISS08 Ver 1.20 firmware loaded on the module.Soldering is fun!
