INSTALLATION INSTRUCTIONS  
PLEASE study these instructions carefully before installing your new MAP Sensor Voltage Clamp for turbocharged or supercharged 1992-  
1998 Honda Civics. If you have any questions or problems, do not hesitate to contact our Technical Hotline at: 1-800-416-8628, from  
7am-5pm, Pacific Standard Time, Monday-Friday, or via e-mail at: [email protected]. Please fill out and mail your warranty  
card. Remember to include the model number of this product in the “Part #____” space. Thank you.  
Description: This MAP Sensor Voltage Clamp limits the voltage sent from the MAP Sensor to the ECU to prevent the ECU from  
“seeing” boost pressure in turbocharged or supercharged applications. 1992-1998 Honda Civic ECUs will show an error code for the  
MAP sensor if boost pressure is read by the MAP sensor. Limiting the MAP sensor output voltage will keep readings at the ECU from  
going beyond the normal range seen on a stock naturally aspirated engine, preventing the MAP error code. This kit includes the  
voltage clamp, attached wiring, and the required splice connectors.  
CAUTION: It is highly recommended to use a heat gun to shrink the shrink wrap around the provided connectors after making  
connections. Use care when using these devices near any flammable material such as carpeting, sound deadening material, etc.  
Keep a Fire Extinguisher rated for use on electrical equipment nearby for added safety.  
INSTALLATION PROCEDURE  
NOTE: Before beginning, make sure the negative cable on the  
battery is disconnected, and that the vehicle is on a level surface  
with the wheels blocked to prevent movement of the vehicle  
while working in and around the vehicle. It is also helpful to have  
a service manual for your particular vehicle on hand for  
reference.  
Intercept the MAP Sensor Signal Wire:  
Locate the MAP sensor signal wire. This is a yellow wire  
with a green stripe located at D-19 (See Fig. 1).  
NOTE: On 1994-1995 vehicles, this is a pink wire with a  
white stripe, located at position D-17. See Fig. 1 for  
reference.  
Cut the wire and strip both ends of the cut wire. Using a  
splice connector, attach the blue wire with a red stripe on the  
voltage clamp to the end of the MAP sensor signal wire that  
leads to the ECU (See Fig. 3), and with the remaining splice  
connector, attach the blue wire on the voltage clamp to the  
other end of the cut wire which leads to the MAP sensor  
(See Fig. 3).  
1. Remove the passenger side kick panel to gain access to the  
factory ECU. (See factory service manual, if necessary).  
Unplug the A & D plugs from the factory ECU.  
2. Follow the wiring instructions as listed below for your  
particular vehicle:

Locate the Ignition Power wire, a yellow wire with a black  
stripe, in position A-25 (See Fig. 1). Cut and then strip both  
ends of the cut wire. With a splice connector, connect both  
cut ends to the red wire coming from the voltage clamp (See  
Fig. 3).

Find the MAP sensor ground wire. It is a green wire with a  
blue stripe. It is located at position D-21 (See Fig. 1). Cut  
the wire and strip the cut ends. Use a splice connector to  
connect both ends of the cut MAP sensor ground wire to the  
black wire coming from the voltage clamp (See Fig. 3).
